It looks to me like you do not have "Keep-alive" turned on.
Check your httpd.conf file for something like this

KeepAlive On
KeepAliveTimeout 5

If it is off then turn it on.

Hi Phallanx, thanks for the reply, that can be done on my internal dev, but I don't think we have access to the httpd.conf files on the hosting server...

Then you can request the host check that they are enabled.

See this excellent set of performance tuning notes for details on how bad a sites performance can be without it turned on.

Phallanx, just wanted to say many thanks for trying to help, but found this:

http://andrewembler.com/web/improving-the-performance-of-zend-cache...

And this has solved the problem, even with cache turned off in the admin section, this was still causing issues, but with:

define('CACHE_FRONTEND_OPTIONS', serialize(array('automatic_cleaning_factor' => 0)));

set in the config/site.php, the site is zipping along dramatically faster! If anyone is having problems with a slow loading site, this is your solution!

Indeed it maybe faster. But I wouldn't have said over 10 seconds to load was acceptable for such a site. I would guess it would be sub 5 seconds with keep-alive turned on. But if your happy; that's all that counts.

Hey Phallanx, I had two different ones up,http://twl.limegreentangerine.net... had some mods from your Miser on it, but not KeepAlive,http://twl2.limegreentangerine.net... has the script with the automatic cleaning factor set to 0.

lol. I'm not a mind reader :P So I will change my comment from "over 10 seconds" to "about 10 seconds"

That site has an error 404 as well as what appears to be no keep-alive.

This is the first solution to the slow load times I have seen that actually showed immediate improvement. On godaddy my non cached pages when from a 20 second to 8 second load time and my cached pages went from 10 seconds to 3. Still slower than wordpress sites I'm running, but this fix finally put my fears to rest about offering CS5 to my clients. Thank you for posting it!

I'm going to give these tips a try, I'm on Dreamhost and have never had a problem with load times for my other two sites, but now with this one using Concrete5 load times are painfully slow.

This seems to work. Noticed a difference straight away!

Well done!

Noticed a big improvement with IE, Firefox still sucks at the load tho....

Also observed large performance increase! Thanks! This just kept some additional hairs on my head!

I know... I'm replying to an old post. But adz' code addition to site.php solution greatly helped increased the slowness a client site of mine was having running C5 vers. 5.5.2.1.

It is like night and day! THANK YOU!
