Results are below. preview of diagramm - http://keep4u.ru/imgs/s/080201/38/38212731c700ec259f.jpg full size - http://keep4u.ru/full/080201/38212731c700ec259f/jpg preview of table - http://keep4u.ru/imgs/s/080201/cc/cc13161af59e01d244.jpg full size http://keep4u.ru/full/080201/cc13161af59e01d244/jpg preview of trace http://keep4u.ru/imgs/s/080201/5a/5a183d74db0fbbd6fe.jpg full size http://keep4u.ru/full/080201/5a183d74db0fbbd6fe/jpg if it is first time open page results are worse... preview http://keep4u.ru/imgs/s/080201/2e/2ea7556bc48f6e377a.jpg full size http://keep4u.ru/full/080201/2ea7556bc48f6e377a/jpg preview http://keep4u.ru/imgs/s/080201/dd/dda92549fab7557f48.jpg full size http://keep4u.ru/full/080201/dda92549fab7557f48/jpg preview http://keep4u.ru/imgs/s/080201/ae/ae49963700a4b92529.jpg full size http://keep4u.ru/full/080201/ae49963700a4b92529/jpg as i see - connect to the MySQL demand alot of time. but it spent only 32% of total time.... How can I tune my enviroment for better results? ===================== Also some of offtopic: why i must login twice? If i want to create new post and not loggin in, site redirect me to the login page. After I insert a correct login and password site redirect me to the login page again! And only second login i return to the forum...
André R.	Friday 01 February 2008 9:23:57 am One reason is that PHP performs badly on Windows compared to Linux, this is something they (PHP and Microsoft) are working on but don't expect miracles. One other reason is eZ Publish, it uses a lot of filesystem calls, something NTFS (file system on Windows) handles a lot worse then most filesystems on Linux. Both on Windows and Linux you should look into tweaking PHP, and adding a PHP accellerator (APC or eaccelerator).

Aleksey Tik	Saturday 02 February 2008 11:41:09 pm Thanks, André. I'll try eZ Publish on Linux next week and try compare it. About filesystem (by the way - i know what is NTFS :) ) - is it have sense placed eZ on RAM disk? The volume of it is not large (32 Mb), so, i can try create RAM-disk... What you think about it?
André R.	Sunday 03 February 2008 8:13:08 am You need a lot more then 32 mb, becuase if you want it to have a effect, you need to have the cache ( but not neciserly the var/*/storage ) on the ram disk. An I recently saw 64Gb used for cache only on a medium install with 9 siteaccesses.. (even though some of the cache size issues on installs with many siteaccesses are looked into). eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
Piotrek Karaś	Sunday 03 February 2008 11:41:19 am > you need to have the cache ( but not neciserly the var//storage ) on the ram disk You mean a RAM cache istead of disk cache in /var/.. ?

André R.	Monday 04 February 2008 1:46:46 am No, he was talking about Ram Disk, a hard drive built with ram. Kind of like Solid-state disk, but it will loose all information if it looses power.. Edit: he probably meant this : http://en.wikipedia.org/wiki/RAM_disk , while I thought ha was talking about this: http://en.wikipedia.org/wiki/I-RAM eZ Online Editor 5: http://projects.ez.no/ezoe \|\| eZJSCore (Ajax): http://projects.ez.no/ezjscore \|\| eZ Publish EE http://ez.no/eZPublish/eZ-Publish-Enterprise-Subscription @: http://twitter.com/andrerom
