I'm very happy about which Linux flavors you have tested. The server for our website, and it's test and dev servers as well, are based on CentOS and my desktop (and development environment) is on Ubuntu =)
Is this anything like page speed for firefox - it seems like it has been improved or am i wrong? I would love to try it but don`t know if it would work on my site http://www.makeasizzlingwebsite.com that i host on Webs.com. If you expand on this post be sure to let me know. Looking forward to trying it.
I am a professional wedding photographer - and have been looking at solutions to speed up my websites.
Extending the cache lifetime of the images on my site sounds great, but I am concerned about the recompression of my images. Will any image degradation be apparent? Will this still happen if I optimize my images manually prior to publishing?
How long has this Apache module be in use on production servers so far? Would be cautious of chucking this on an important sites server if its fresh out the door with no real world usage yet.
Installed 64bit version on Ubuntu running Apache 2.2.8 this evening early tests seem promising using an ecommerce site on the server as a testbed http://www.jndarts.com 14.1 secs without 9.7 with. Strange things happen if you reload the same page though 5.1 without 8.1 with. Tested using Pingdom tools
As Coops pointed out, I would be hesitant to placing this on shared servers. It seems to be that doing all that on the fly processing is going to significantly increase the overhead on the server itself.
Very nice and impressive article you have posted. Its very helpful, i have read and bookmark this site and will recommend it to more other peoples. Lizard Labs
I tried this on my server. Ubuntu 10.10 64 bit running Apache2. Seemed to work okay but some requests would just hang randomly. I never had that problem. I disabled mod_pagespeed and the hanging problem went away. Any idea what could be causing this?
Planning to try this mod_pagespeed. If it works without any issues, will probably add it to our server which powers http://www.cubrid.org, the home page of CUBRID open source database system. Let's see the difference.
I'll try it too on a CentOS server that is powering an online game http://www.raceconflicts.com and let you know how it goes. Have high hopes in this couse speed is very important for me.
I'm not so crazy to run that mod on my producttion server ;) Right now I installed the mod on my local testing server (Ubuntu 10), just to see if something breaks.
Do you think you can install that mod on a server where a controlpanel is used (cPanel, Directadmin...)
Has anyone run apache benchmark on this in a realistic environment. As others have said it seems like a LOT of server overhead per process, but we may be overestimating how expensive that is. I'm just not sure.
@Matt Andrew: DreamHost already has mod_pagespeed set up for customers to take advantage of! You can access it via the webpanel. Check it out: http://bit.ly/bGFbBX & spread the word...
locks up my apache too. apache server procs just sit in W and never terminate. eventually i run out of server procs and the sit is wedged. need to restart then. nasty.
we fixed up the logs issue and some deadlocks that were happening. the svn tree has those fixes and we'll be making packages available on Monday. Thanks for trying out mod_pagespeed!
mod_pagespeed attempts to preserve image quality of jpegs as much as possible; there are only very small differences between images before and after recompression. That said, if you are already optimizing your jpegs for download size at a given quality level, you may discover that mod_pagespeed attempts to optimize but decides the results were not worthwhile.
The best way to decide if image optimization helps you is to try it out. If you don't like the appearance of the resulting images (I know that photographers are more keenly sensitive to small changes in jpeg compression quality), or you discover they don't seem to be rewritten at all (the image_rewrites statistic doesn't increase much after you've surfed for a while, but other statistics increase as you'd expect), then you may be better off turning off that specific filter. You can leave everything else on and still see benefits.
I have installed the mod_pagespeed to one of our servers and am VERY pleased with the results. One of our clients has a large wordpress site and even with best practices implemented was taking to long to load. This mod literally off seconds and the site is loading like a champ. I want to Install it on my other servers; however, there are many legacy sites running PHP4 and http 2.0 on them. Does anyone know if this mod would effect them adversely? Appreciate the input and good post!
Sounds great !

ReplyDeletenice... look forward to playing with it
ReplyDeleteDo you guys have a testbed with and without mod_pagespeed accessible externally, so users can try and "feel" the effects on their environments?
ReplyDeleteWill this be turned on automatically for all existing blogspot blogs?
ReplyDeleteNice to know. Looking for it ahead.
ReplyDeleteAny plans to support Apache 2.2 on windows?
ReplyDeleteI'm very happy about which Linux flavors you have tested. The server for our website, and it's test and dev servers as well, are based on CentOS and my desktop (and development environment) is on Ubuntu =)
ReplyDeleteI will be trying it this weekend :D Thanks
Fantastic. I wonder if you could set it up to work with Dreamhost too - I know you partner with them for other things.
ReplyDeleteInstalled :D, lets see how this handles!

Get this on Bluehost too please! I'll make sure to ping them about it too!
ReplyDeleteVery nice glad to see Google's money going towards projects that make the web a better. will be measuring the change with analytics event tracking.

Will Windows be supported?
ReplyDeleteRepeat: but trying to give some weight!
Please support FreeBSD.
ReplyDeleteRegards,
Does it work on Gentoo Base System version 1.6?

ReplyDeletehow it will be possible and is there is any trick is available ?
ReplyDeleteI'm surprised no one has asked this yet...
ReplyDeleteThe module may be good on a per-page basis, however what's the overhead on the server?
Surely doing all these on-the-fly modifications to your output will have en effect on your overall server-level performance?
Does this module only have a place on shared hosting platforms rather than high performance bespoke platforms?
How long has this Apache module be in use on production servers so far? Would be cautious of chucking this on an important sites server if its fresh out the door with no real world usage yet.
ReplyDeleteThis is very cool and funny timing: just posted slides from a recent talk I gave on Web UI performance tuning: http://www.slideshare.net/apemberton/ui-performance-tuning

ReplyDeleteok good job google it uses all the speed up filters you need. Easy to use for none linux gurus.
ReplyDeletewww.up2city.de 1.02 seconds without
0.90 seconds
but i already patched our server! so its ok
@mick 14,1 !!!!! thats too much !! change the hoster or using php cache...

ReplyDeleteWell, I forwarded this blog url to my network administrator to look into google page speed, and this is the reply I got instantly :
ReplyDelete"Is http://code.google.com/speed/page-speed/docs/using_mod.html running it because its been down all morning."
add it to lighthttp please!
ReplyDelete@Matt Andrew: DreamHost already has mod_pagespeed set up for customers to take advantage of! You can access it via the webpanel. Check it out: http://bit.ly/bGFbBX & spread the word...
ReplyDeleteDreamHost just enabled this for all their customers: http://blog.dreamhost.com/2010/11/04/mod_pagespeed-now-available/
ReplyDeleteI did some tests and it blew off my error.log to 31GB in short time.
ReplyDeleteI think this module is a good start but for CMS, Forums or Blogs it is not usable...
It threw too many errors with php driven sites. I will investigate some more
locks up my apache too. apache server procs just sit in W and never terminate. eventually i run out of server procs and the sit is wedged. need to restart then. nasty.

ReplyDeleteHow can i implement this apache module in my site?
ReplyDeleteWhat are the steps that i need to follow..
If you are looking for dedicated servers, then check out BlueMileCloud.com.
ReplyDeleteMake your websites run faster, automatically -- try mod_pagespeed for Apache.
ReplyDeletenice posts, thanks for sharing.. please visit my blog
Thanks for this. Will love to try this out.
ReplyDeleteThanks for such tool.
ReplyDeleteI think it should be incorporated with Google Webmaster Tools
Is FreeBSD supported?
ReplyDeleteI've done many tweak in my .htaccess for me to speed up my site. But this is another tool for me to use. Thank you.
ReplyDeleteSounds Great !
