Hello 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'; Code (markup): so the forum start use this cache but i have a problem on my server. xeon quad 16gb ram 4xsas disks raid 10 Cpanel server: Nginx in front of Apache 2.2 + prefork Php as fastcgi prefork settings: StartServers 8 MinSpareServers 10 MaxSpareServers 10 MaxClients 256 MaxRequestsPerChild 20000 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 workers(childs) the key is, php as a fcgi manager should be the parent of worker childs. Code (markup): Can anyone help on this what is wrong and how can i fix it? Thank you
