There are a lot of good resources on the internet about performance optimization you can look up. In this article, tough, I will focus on things that really helped us to run the game even on old devices while keeping a good level of graphic quality. I will try to keep it as simple as possible and easy to understand without going into too much confusing technical details. Draw Calls can have quite a huge impact on the performance of a game – especially on mobile devices.
Thankfully Unity got a couple of tricks up it’s sleeve to reduce draw calls by batching! Static Batching, on the other hand, requires objects to be marked as static in the inspector window. Since every material uses a draw call you should reduce the number of materials you’re using in your game. A UV-map of a model tells the shader where the object’s polygons are located on a texture image.
If you only use a fraction of a full-size image for your object’s UV-map, you can fit more UV-maps from different objects on one image. As a result, you have one material rendering multiple objects in your scene simultaneously using one draw call because of Unity’s Dynamic Batching.
Obviously this only works with objects and lights that are static and won’t change their position during the game. There’s a lot of information on how to bake lightmaps in Unity available on the internet. You can set the scale by selecting a mesh renderer in the Hierarchy and go to Object in your Lighting inspector window. They probably will fix this in the future, but for now – no Normal maps on baked objects. You can get away with a low polycount by using Normal maps to add details onto your mesh (if you don’t bake lightmaps for them).
Occlusion Culling removes models in runtime when they are out of sight of the camera so they will be ignored by the renderer. I hope you found some useful tips and tricks in this article and we were able to help you boosting your game’s performance! Millions of Americans wanting to enroll in Obamacare use the official website. The home page of grew significantly in size and complexity over the past year. With the larger page size and complexity, the page load times and "above the fold" times increased proportionally for So the site is clearly larger and slower, but how consistent is the response time under load? One nice feature about the website is that you can create your health plan in stages, and come back later to finish (see Figure 7). Unfortunately selecting a dental insurance plan spawned the following error repeatedly, despite numerous phone calls to the help line (see Figure 8).
While the website has improved in availability and consistency, performance problems remain one year later. This article evaluates the website performance issues of the site, and offers some solutions to improve speed.

Summary: Google's new search rank measure, site speed, is one more reason to make sure your pages fly. With Google now factoring page loading speed into search engine rankings, having a fast website has become even more important. A web performance audit is an independent analysis of the factors that contribute to the response time of a website.
A hybrid performance audit combines both front-end and back-end analyses into one complete report. Figure 1 shows an example of a long time to deliver the first byte, over 4 seconds before any data is sent. When browsers load and execute JavaScript they stop other rendering duties including downloading other resources.
One trend that we're seeing lately with the advent of Web 2.0-enabled pages is the growth of JavaScript. One of the useful metrics that Page Speed gives is an indication of how much of the CSS is actually referenced in a target web page.
HTTP compression is a standards-based way to compress the textual content of your web pages. On average images make up 64.3% of the average web page size, and more than 75% of all HTTP requests, so optimizing images is one of the first places to start when speeding up web pages. You can detect certain server settings without requiring access to the server, typically using HTTP headers.

With speed now factoring into web page rankings, web performance has suddenly become more important.
Using the Googlebot, Sreeram analyzed both 380 million top sites and 4.2 billion websites to see what the average web page consists of. 1990?? ?? ????? ????? ???? ???? 315K? 50?? ???? ?? ?? ??? ???? ?? wireless ? ??? ?? ???? ?? ????? ???????.

Before we discuss further about the various web performance optimization strategies, let’s discuss what actually web performance optimization is. Web performance optimization refers to the various tactics that helps in enhancing the speed in which the web pages are downloaded and exhibited on the visitor’s web browser. The strategies that contribute to effective web performance optimization includes a set of processes that deals with programming, coding, configuration, user interface plan, meta data, photos and written content.
Analysis of keyword research – It is important for you to do a good analysis of keywords that you have chosen for your websites.
Reputation, popularity and saturation level the website – You need to find out more about the saturation level of website. Use of proper web performance optimization tools – There are effective web optimization tools that would help you know about the exact status of website. Keeping a close look on the performance of your website is crucial if you want to earn good rewards. This saves a lot of computation time since shadows and light behavior don’t need to be rendered in realtime. If you leave every object at a scale of 1 you end up with a lot lightmaps which has an impact on the game’s performance because it increases draw calls and needs more texture memory. Therefore we were able to delete a lot of polygon from the backside of the objects, since they’ll never be seen by the player. I know… lots of 2048 textures look great in your game but they eat a lot of memory as well.
The best is to play around with the settings and see with how much you can away before the game starts to look bad.
Just over one year ago, health care consumers were directed to log on to the website starting on October 1, 2013. Page size grew by 85% from 677K to 1252K (see Figure 2) and total objects grew by 172% from 40 objects to 109 objects (see Figure 3).
Users seeing this error are told to wait a while to see iand try again, or delete their 2015 plan and create a new one.
In the larger waterfall you'll notice the Home.png main banner image loads slowly, it was 471K! This is smaller than the average top 1000 page size (1807K) and about the same as the average number of objects (114, source home page response times have slowed down by 62% to 78%, while page size and complexity have grown by 85% to 172% over the past year. A brief analysis shows a number of issues that could be addressed to improve the user experience. The site showed some improvements in "above the fold" speed, but slower load times than the old version.
Exactly how much of a factor speed is in search rankings is open to debate, although anecdotal evidence suggests that speed can affect rankings. In addition to measuring the size and rendering speed of the various components that make up a web page, a web performance audit should offer recommendations to speed up the response time of initial and subsequent page loads.
Front-end audits are more common than back-end because about 80% to 90% of the time users wait for pages to load are spent on the front-end (Souders 2007). Back-end audits typically review server setups, CMS and module configuration, and SQL query efficiency. Hybrid audits analyze the two main components that contribute to web page speed, the server configuration that delivers the content to the user, and the content itself and how quickly the content renders. Performance experts use these and other tools to analyze your site, review your code in detail, and triage and implement recommendations. Misplaced JavaScript (typically placed after CSS instead of before), can block the downloading of subsequent files.
Multiple objects (external JavaScript and CSS files typically) within the HEAD of XHTML documents are particularly harmful to web page performance because they delay the rendering of useful body content that users can interact with.
Libraries like jQuery, Prototype, YUI, and Dojo are used and combined with other behavior (menus in particular) to create more interactive and responsive web interfaces.
HTTP compression or "content encoding" uses GZIP and deflate to compress your XHTML, CSS, and JavaScript at the server, and modern browsers decompress these files automatically to speed up web page downloads and save bandwidth. While lossy methods can significantly reduce web image sizes, not everybody wants to change the quality of their images. Caching, keep-alive, HTTP compression, etags usage, cookies on static resources, and other settings can be detected remotely.

Steve Souders wrote his first book on web performance gives 14 rules to follow to speed up your site by 25 to 50%.
Gives waterfall charges of resource loading sequences, optimization checklist of major problem areas, and timings at different network locations and bandwidths of page loading metrics.
Explores the history of the Internet and the Web, response time research, and how this research relates to the Web. States the problems to be addressed and the framework as well as approaches for addressing the problems. This chapter introduces two Web page response time measurement methods (the Muffin proxy, and the Frame method), which allow response time to be decomposed into three of its constituents, i.e. This chapter explains the complexity of Web pages from two perspectives: creation and content. This chapter shows how Web page response time and responsiveness can be monitored and estimated based on server access log analysis. Describes two scenarios to show how the measurement, modelling, and monitoring modules can be used in Web page design to produce Web pages that deliver satisfactory response times. It’s true that websites that are not on top positions on search engine fail to get the attention that it should get. It’s important to keep a tab on the speed at which the web pages are downloaded as faster download and display speed increase visitor retention, user satisfaction and loyalty.

The site didn't have as many "waiting room" delays as before, but still spawned a few errors (see Figure 6). This was our initial analysis of the site shortly after it officially launched in October 2013.
One of the first steps companies need to take in improving their website speed is a web performance audit.
Depending on its depth, a web performance audit can also include optimized code examples to replace older less efficient code (XHTML, CSS, JavaScript, and backend PHP, Perl, Java, etc.).
Back-end audits are still useful for performance because you can potentially gain orders of magnitude improvements in performance from back-end optimization. A long TTFB indicates a server performance issue, typically from an overloaded shared or dedicated server. Here is an example where JavaScripts were placed between CSS files (see Figure 3), note the misplaced CSS file after a JavaScript file. To combat CSS bloat remove legacy CSS left over from past designs, and adopt a more object-oriented approach ala Nicole Sullivan (see for more information). Even though on average HTTP compression can save 75% or more off of textual files, only 66% to 89% of compressible text is compressed on the Web (Ramachandran 2010).
You can losslessly trim unnecessary bytes and blocks from your images using a tool like Smushit from Yahoo!
Web analytic tools would help you understand what is happening to your website and measure your website’s success. Recent survey has proved that more than 70% percent of Internet users do not go beyond first or the second search engine pages. You can also make use of validators to check the invisible parts of the website and the potential problems that is retarding the popularity of your website on popular search engines.
They are equipped with all helpful strategies that can help in analyzing the success of a website. A couple solutions present themselves, compress the JavaScript (with GZIP or deflate) which typically compresses these text files by 75% to 80%. The majority of analyses are front-end, although back-end audits can often reveal significant areas for improvement. So, as a smart online business, you should implement strategies to push the ranking of your website on top positions.
You can make use of some good online tools to find out more about the popularity of the website.
A Reliable web optimization company would also help you identify the key problem areas that are pulling down the popularity of your website.
We showed some common problems found in websites today, and list some tools used by performance engineers.
Interestingly, the top sites network size (bytes delivered down the pipe) was smaller (312K vs. This is where better web performance optimization tools can help you improve your ranking on SERPs. The best solution is to rethink the behavior of the page in question, and substitute standards-based methods (CSS drop-down menus for example) for JavaScript.
