Site Speed reports to analyze your site’s page load times. To help you measure and diagnose the speed of your pages in a finer grain, we’re happy to extend the collection of Site Speed reports in Google Analytics with User Timings._trackTiming API included in ga.js (version 5.2.6+) for reporting custom timings. This API allows you to track timings of visitor actions that don't correspond directly to pageviews (like Event Tracking). User timings are defined using a set of Categories, Variables, and optional Labels for better organization. You can create various categories and track several timings for each of these categories. Please refer to the developers guide for more details about the _trackTiming API.Here are some sample use cases for User Timings
To track timings for AJAX actions before and after onLoad event.
A site can have their own definition of "User Perceived Load Time", which can be recorded and tracked with user timings. As an example, news websites can record time for showing the above fold content as their main metric instead of onLoad time.
Detailed performance measurement and optimization of sub components on a page, such as time to load all images, CSS or Javascript, download PDF files and time it takes to upload a file.
Want to check out User Timings Report in your account? Explorer tab on the User Timings report shows the following metrics by Timing Category, Timing Variable, or Timing Label (all of which you define in your timing code ).
Avg. User Timing—the average amount of time (in seconds) it takes for the timed code to execute
User Timing Sample—the number of samples taken
The Explorer tab also provides controls that you can use to change the tabular data. For example, you can choose a secondary dimension—such as browser— to get an idea of how speed changes by browser.Performance tab at any point of navigation in the Explorer tab, such as after drilling down on a specific category and variable, to visualize distribution of user reported timings. The bucket boundaries for histograms in Performance Tab are chosen to be flexible so that users can analyze data at low values ranging from 10 milliseconds granularity to 1 minute granularity with addition of sub-bucketing for further analysis. Map Overlay tab provides a view of your site speed experienced by users in different geographical regions (cities, countries, continents).Satish Kambala and Mustafa M.

Cross-posted from the Google Africa Blog Creating applications and services that use Google platforms to make the internet more relevant to Africans is a big part of Google’s vision in Africa. This is why we are always excited whenever we come across individuals or companies whose efforts are in line with this vision. Here are a few of the interesting applications we have seen in recent months. Battabox , co founded by Christian Purefoy and Yemisi Ilo, is an online social television platform developed in Nigeria that aims to provide everything Nigerian from music, film, street-life to news, comedy and cooking using the YouTube platform. Crowdsourcing videos is an important part of the Battabox strategy and they were able to achieve this using YouTube Direct running on Google App Engine integrated into their website. They also provided an Android App that enables users to upload videos directly from their Android phones.
Battabox website screenshot There are many other examples from further afield. In South Africa we met Nomanini who have a Google App Engine backend for Lula , their airtime vending device, which promises to change the way airtime is distributed in the region. Envaya SMS is an amazing application that turns your Android phone into an SMS gateway and has been used by many NGOs in East Africa. SAF SMS is a school management solution built with Google Web Toolkit that has been adopted in more than 100 schools in Nigeria. We also met Serengeti Advisers , a consultancy firm in Tanzania that uses Google Chart Tools to create interactive reports on their website.
Nomanini’s Lula terminal communicates with a backend powered by Google App Engine As part of our drive to meet and interact with app developers in Africa, our Android Developer Relations team also recently hosted the developers of AfriNolly and the Nigerian Constitution Android app on their weekly Android DevRel office hours hangout on Google+ for Europe, Middle East and Africa . At the hangout, these African developers shared information about their apps with other Android developers.
You can follow the exploits of these and more developers in Sub Saharan Africa as they continue to make things happen with Google APIs and platforms by keeping an eye on our case studies page .
Do you feel your app should be featured here? Let us know!

By Matthew Steele and Bryan McQuade, PageSpeed , Google Chrome , and the SPDY protocol , among other efforts. In December of 2011, to make it easy for you to enable the SPDY (pronounced "SPeeDY") protocol on your sites, we released an early beta of mod_spdy, an Apache module that adds SPDY support to the Apache HTTPD server. We’ve spent the last few months working with our early adopters to fix bugs and tune performance of the module. Today, we’re launching a version of mod_spdy that we encourage you to try on your web server.Installing mod_spdy mod_spdy Debian or RPM package for your platform, or compile from source . Once installed, your Apache server will begin using SPDY to communicate with SPDY-compatible browsers (e.g. Google Chrome, Android, and recent versions of Firefox). SPDY runs over HTTPS, so any HTTP (non-HTTPS) traffic on your site will not be affected by mod_spdy. Further, since SPDY requires server-side support for the NPN TLS HTTPS extension, which is not available in most current Apache environments, a version of mod_ssl with NPN support is included with the mod_spdy packages.The server and browser can compress HTTP headers, saving bytes on the network.
Multiple resource requests can be multiplexed over a single TCP connection, saving connections on the network.
The browser can request all page resources at once instead of a few at a time, which reduces the number of network round-trips needed between server and client.
VIDEO How mod_spdy works in Apache Download mod_spdy for your platform and give it a try, and let us know what you think on our mailing list . mod_spdy is an open-source project and we welcome contributions. We are continuing to add new features, tune performance, and improve support for up-and-coming versions of the SPDY protocol.Matthew Steele and Bryan McQuade are Software Engineers on the Google PageSpeed Insights Team in Cambridge, MA. When not working on mod_spdy, they focus on developing tools to help site owners understand how to speed up their sites. Posted by Scott Knaster , Editor

By Scott Knaster, Google Developers Blog Editor Google Chrome Canary . There's a new version of Chrome Canary pretty much every day, and it gets the latest features. Of course, because it's built every day, sometimes it’s not very stable and it falls right off the leading edge it's balanced on. That’s why, for safety, you can install and run the stable version of Chrome alongside the Canary version.see the documentation .Rube Goldberg Machine Contest at Purdue University.

By Navneet Joneja, Product Manager, 1. Network Serve the request from as close to the user as possible
Optimize the network routing between the end-user and the service, including avoiding pockets of network congestion and minimizing the number of network hops between the user and the service.
2. Storage Google Cloud Storage is built on Google’s proprietary network and datacenter technology. We’ve spent more than a decade building out proprietary infrastructure and technology to power Google’s sites (after all, we believe that fast is better than slow ). When you use Google Cloud Storage, the same network goes to work for your data.
We replicate data to multiple data centers and serve an end-user’s request from the nearest data center that holds a copy of the data. We also offer a choice of regions (currently U.S. and Europe) to allow you to keep your data close to where it’s most needed. We then take this one step further. When you upload an object and mark it as cacheable (by setting the standard HTTP Cache-Control header), we automatically figure out how best to serve it using Google’s broad network footprint, including caching it closer to the end-user if possible.
Finally, you don’t need to worry about optimizing your storage layout (like you would on a physical disk), or the lookups (i.e. directory and naming structure) like you would on most file systems and some other storage services. We take care of all the "file system" optimizations behind the scenes.
Google Cloud Storage , we do all the background work to make it fast so that you can focus on your application.Navneet Joneja loves being at the forefront of the next generation of simple and reliable software infrastructure, the foundation on which next-generation technology is being built. When not working, he can usually be found dreaming up new ways to entertain his intensely curious almost-two-year-old. Ville Aikas likes to work on tools and services that make developers lives easier and "just work". When not busy cranking out code, he loves to play soccer with his kids, build robots and watch F1.
