I was try to use xcache and it realy helps my server and i was add also in config.php the line:
$INFO['use_xcache'] = '1';
so the forum start use this cache but i have a problem on my server.
4xsas disks raid 10
Nginx in front of Apache 2.2 + prefork
Php as fastcgi
When i have for example users 10 and latest user that register is user test1 when i use another browser and register another user so i can have users 11 and latest user test2 when i refresh sometimes i got the correct stats and then if i refresh again or browse the forum for a while and go back i can't see the new stats and instead i have again users 10 and latest user test1 and this happend also on topics.
I was ask the author of xcache and he told me this:
The current looks you have is: httpd as fcgi manager, managing many
php-fcgi workers(childs). it not only make your stats wrong but also
take up a lot of memory, because each php-fcgi worker allocate its own
XCache cache memory
the target result should be: _1_ php-fcgi parent, with many php-fcgi
the key is, php as a fcgi manager should be the parent of worker childs.
Can anyone help on this what is wrong and how can i fix it?
*Also i want to ask about Disk storage what i must enable to use this:
$INFO['use_diskcache'] = '1';
and which folder is using and what permissions i must add there?
Correct me if I'm wrong and going of your recent threads but you have:
I can only imagen your memory and I/O usuage is way to high :o , So what is the current memory usuage :whistle:
And what exactly are you trying to achive. All those caching and static methods will cause extremely high usuage on your machine, I cannot think why you would benefit by using all those and more of all your /tmp filling up very very fast by the second.
[*]php as fast_cgi / mod_cgi
so what do You recommend
I've similiar config and the server is working very very nice in comparision to the previous configuration with apache without memcache
It may work fine don't get me wrong but I guarentee the I/O will be high. I do hope you have some script to flush the /tmp directory from sess* every so often.....
Everything will be fine I just do not think the idea of fast_cgi / xCache and nginx in place running at once is disc healthy.
Thats just my opinion though.
