Slow site = config problem?

Geraint Edwards	Thursday 14 July 2005 3:11:49 am Even with viewcaching and template compilation enabled my test server's performance (v.3.60) is very slow. The base index page (after compilation/caching) is taking c. 0.5 secs to load. I've done some testing, peppering the code with timing points and discovered that anout 30% of this time is take by the following line: require_once( 'kernel/classes/ezcontentclass.php' ); This file only contains class definitions and doesn't execute anything as far as I can tell. Does this suggest that I am hitting some memory constraint in apache such that a swap file is being used at this point or could the file be on a dodgy bit of disk? Probably not this since loading it from a second disk makes no difference. Any suggestions would be most welcome. Geraint
Geraint Edwards	Thursday 14 July 2005 11:23:44 am I've now rebuilt php with --enable-memory-limit so that I can track memory usage. The results are rather alarming! A really basic page (already view cached & compiled) uses 9460KB of memory and the time bottleneck I'm seeing coincides with an increased usage from 2247KB to 5570KB. More complex pages/templates use even more! Does eZPublish really need to use this much memory? Geraint
Geraint Edwards	Thursday 14 July 2005 12:06:57 pm Ok - some rooting around and I find some comments about APC reducing memory usage. So I've tried it out and get the following approx results: No accelerators 0.50 secs 9.4MB php_accelerator 0.23 secs 9.7MB APC 0.14 secs 1.1MB I think I have my answer.
Paul Borgermans	Thursday 14 July 2005 12:22:25 pm Hi Geraint Yes, eZ publish is resource hungry (both RAM and CPU), even with a php accelerator and some fairly simple presentation logic in templates. If you ever are to be slashdotted, turn the static caching on which is available from 3.6.x :-) -paul eZ Publish, eZ Find, Solr expert consulting and training http://twitter.com/paulborgermans
