Posted January 12, 201114 yr Hello I am using xcache and i add also the:$INFO['use_xcache'] = '1'; On the config of the forum. Does that means that it will cache other things than php requests? And my second question is as i want to use memcache for static files and xcache for dynamic which line i must add to the forum config? Please give me some info. And the third question :) Do i have to compile from easy apache update on cpanel the memcache and the memcached? I think memcached is for php.. Memcache will work alone? Thank you
January 12, 201114 yr I'm a bit curious. Are all these optimizations going into one server? I see you posting on cpanel a lot, so I was wondering if you were building a massive server fleet. My piece of advice. If this is all for one box, I'd step it down. I've managed sites with 1000+ online at once with nothing but a optimized apache w/ nginx. It does become overkill running all these pieces of software at once. Even if you have 16GB of RAM to handle it all, it still takes CPU cycles which still affects the system.
January 12, 201114 yr Author Yes it is for one server only but i do not use all of them :) Some questions are to learn a few things :) Can you please send me a pm from a forum with no more than one server and no more than 16ram that is using nginx in front of apache with more than 700 users online please to check it? Thank you
January 12, 201114 yr Author Ok thanks for the pm iBotPeaches :) I will wait for other members also to send me some info about my questions on my topic.
January 12, 201114 yr Why not share it here. :) So if next time someone has same question he can look at this topic :)
January 12, 201114 yr People will assume nginx is good... It made things bad for me :P NO IPB forum should use 16GB alone.. thats Crazy ! If I hosted someone that used that they get instantly suspended, Hense the reason IPB set a limit of 128MB ? I have been doing work on a server from an IPS client, They are a very active community and there memory usuage is around 6.2MB and it's more or less image heavy. ( IPB 3.1.4 ) I read through your setups / posts / topics on here and cPanel.net and with all those mods no wonder it's going heavy on resources. post the FULL output of these command's via SSH:iostatnetstat -an | grep 80 | wc -l
January 12, 201114 yr Author I was fix my problem as i had a wrong value on nginx config. Yes please check and tell me what you think about my I/O is it ok? iostat: avg-cpu: %user %nice %system %iowait %steal %idle 18.75 0.04 7.85 0.03 0.00 73.33 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn sda 70.90 11.19 990.49 8844356 782716320 sda1 1.19 0.31 27.94 241858 22076848 sda2 2.54 3.69 91.25 2918652 72105224 sda3 63.75 5.59 720.77 4418028 569572800 sda4 0.00 0.00 0.00 8 0 sda5 0.00 0.00 0.00 1621 0 sda6 0.21 0.01 7.73 8130 6108256 sda7 3.22 1.59 142.81 1255619 112853192 Thank you

January 13, 201114 yr I/O wait time seems good but not a fan of the average CPU user. Where is your MySql located ? Have you moved this to a partition of it's own, If not I suggest you do as WHM can be heavy on read and write with all the functions that cPanel needs so moving it to a disc whats not currently active will increase performance. If I was you I would remove nginx and stick to apache, Use SPRI to control the processes.
January 13, 201114 yr Author not a fan of the average CPU user What do you mean? It is not ok?Where is your MySql located ? Have you moved this to a partition of it's own, If not I suggest you do as WHM can be heavy on read and write with all the functions that cPanel needs so moving it to a disc whats not currently active will increase performance. It is on the same disk with beb server files. But i am using 4x raid 10 sas disks 15k and i was ask for a fast ssd and the datacenter told me that they have the intel that is good one but the value version and not the enterprise that is much faster but more expensive and they told me also that my raid 10 will perform better than the option to add the extra ssd intel value .... I am not sure if it true .... I was fix my problem no problem now but i am looking for caching statics files and i am done :) But i have already xcache and i can't use or i don't know how to make them work together as i can add the config lines on the config.php from one of them..... Thank you :)
January 14, 201114 yr Well you have a very active community with plenty of space so you should move your mysql for better performance. I do the same on all of out boxes, Have a 15K disc just for mysql and we never see any I/O issues or such. Speeds are great to.
