very slow site

[thumbsucker]

Hmmm.

My problem seems to have come back.  Taking periodically 13-15 seconds to load the home page.

thumbsucker, try taking the non-linux index file from this zipfile, swapping it for your index.php, and tell us how much cpu time taken in addition to the clock time.

Hi,

My site seems to essentially be dead for large parts of the day in terms of performance.  I'm running on a virtual server with 256MB of bustable memory.

Ran the test now and got the following:

Generated in 26.883395 wallclock seconds, 0.33 CPU seconds, latency ratio=81.4648333333 by CMS Made Simple 0.11.2 (cached) using 15 SQL queries -->

I'm depressed.

You might want to test out the new .12 beta2. and the .12 final. They both will have tons of speed improvements.

[thumbsucker]

Do you think it won't be a problem trying out the beta for 1 week then switching to the gold release?

I just don't want anything to break and cause a lot of work, but am willing to do it for the speed improvements...

[lemkepf]

I'm not promising ... but give it a shot and try it. Let the dev's know if it worked for you.

[thumbsucker]

The instructions say "overwrite" every file on the server with the beta files.

But wouldn't that eliminate the modifications I've made to get my current site up such as templates, style sheets, etc?

[lemkepf]

It will overwrite any files... but all the stylesheets and templates are stored in the database. (i'd do a backup of the files anyway)

[LeisureLarry]

Or just do the testing in another folder and with a second database if this is possible.

[thumbsucker]

I tried the beta and it broke my site.  Had to roll back to my older version.

Still getting slow as molasses performance 20-30% of the time. 

My host thinks it has to do with persistent DB connections, although I clearly set that to false in the config fie.

Any thoughts?  I can't imagine I'm the only one who's run into this problem?

[LeisureLarry]

Why did beta break your site?

I changed my hoster and use the beta and I´ve really great performance now.

Greats Larry

[lemkepf]

Yea, what specifically about version 12 broke? Also... just for giggles... install it in a clean DB and new directory and see if you get the same issues.

I got script errors.

What's the best way to upgrade a version while keeping all present content, templates, etc?

I got a message from my host saying I'm exceeding CPU and RAM usage, so I'm curious how resource intensive CMS Made Simple might be....

[LeisureLarry]

Upload all files of the new version and run uppdate.php instead of install.php. That should be all. But for 0.12 you have to change your templates because the old smarty tags for the menu aren´t supported any longer.

I agree with "sloop" (above in this thread) : serving pages is a static job, with no latency problem, no db access and even no CPU for PHP. Building/generating a page may take up to 15s but it should hurt the publisher only, not the surfer. Please see : http://forum.cmsmadesimple.org/index.ph ... 678.0.html

Whenever a page is changed, the static file is erased so the rebuild page is... changed

Hope it helps
