Google open sources Apache server speed mod
Googlenet mystery server bits?
Google has open sourced an Apache server module designed to speed website performance. Presumably, the module is based on the mystery Google Web Server the company uses to serve its own pages.
Known as "mod_pagespeed," the Apache module speeds performance "on the fly" in 15 separate ways, which include optimizing page caching, minimizing client-server round trips, and reducing payload size. "mod_pagespeed is an open-source Apache module that automatically optimizes web pages and resources on them," Google says. "It does this by rewriting the resources using filters that implement web performance best practices. Webmasters and web developers can use mod_pagespeed to improve the performance of their web pages when serving content with the Apache HTTP Server."
Google says it has seen the module reduce page load times by up to 50 per cent on a random sample of sites. "In other words, [it's] essentially speeding up websites by about 2x, and sometimes even faster," the company said in a blog post.
Google shows off a sample test here:
Google says it's already working with GoDaddy to run the Apache module with "many" of the hosting outfit's 8.5 million customers, and it's partnering with Contendo to integrate the module with that company's content delivery network.
You can download the module here. Google offers 32-bit and 64-bit binaries, and it has been tested on CenOS and Ubuntu, but it may also run on other Debian-based and RPM-based Linux distros. It requires Apache 2.2.
According to the latest study from UK research outfit Netcraft, the Google Web Server — a custom-built server originally based on Apache — now runs nearly 13 per cent of all active web sites. This includes not only Google's own sites, but also the sites it runs on behalf of third parties via services like Blogger, Google App Engine, and Google Sites.
Apache is the most prevalent server on the web, running 53,651,190 active sites, compared with 16,118,218 run by Microsoft servers and 11,978,680 run by Google Web Server (aka GWS, pronounced "gwiss"). But GWS is only run within the Googlenet.
Asked if its mod_pagespeed Apache module is based on GWS, Google did not respond. But it's typically tight-lipped about its internal technology. A former Google employee has told The Reg that GWS was originally built from open source Apache code. But, according this ex-employee, the server has been so heavily modified over the years that it now bears little resemblance to Apache. It's packed with custom I/O handles, he says, that interface with Google-specific remote procedure calls.
But Google is presumably using the speed optimizations it's now offering to world+dog through the mod_pagespeed module. The module's open source project is here. ®
re: erm....... ..
The gpl license requires that you provide source code with any binary, and allow further modifications.
Since any binaries stay firmly within Google-land, there is no requirement to distribute the source to anyone.
And in any case, Apache HTTPD use the _Apache_ license, which has no modified source distribution clauses.
So Google can do whatever the hell they want with it.
I rose to the trolling..... am I going to hell?
The Clue is in the Name
Apache uses the "Apache License" which allows modifications to be kept private.
Isn't Apache licensed under the GPL? -- Not by a long shot.
And isn't there a "viral" clause in the GPL stating that any modifications made to GPL software must also be released under the GPL? -- Not by a long shot.
So - does this mean that Google were in violation of the licence by not releasing the source code to the modification? - Not by a long shot.
what other GPL software they've made changes to and aren't releasing the source in violation of the licence. - Not by a long shot.
Has the GPL actually been tested in court yet? - Several times over.
I wonder if the FSF has the cash and stones to tackle a company as big as Google on this issue -- Does it need to? I mean, according to someone who actually knows at least a tiny tiny tiny bit about this subject?
This is the most entertaining post I've read in weeks. Incredibly misinformed person using charmingly assertive and confident tone, almost fooling the unalert. You must be an Oracle salesperson.
