Hi, After running LiteSpeed for 1 weeks, seems i the server run fast (when user around 100-500online) but still not happy enough with LS, even still having issue on LS Cache. I need some tips from LiteSpeed Staff for my configuration. My configuration is not tuned very well. Hope you guys can look at my current setting. This server is running social network application (phpFox). Currently have 28K member register and average user online 500-1000 online members. We have 2 server with running Dedicated Web server(LiteSpeed) and Dedicated MySQL Server(MariaDB). Webserver Spec : 8CPU/24GBRAM/250SSD/1000Mbps Port MySQL Spec : 8CPU/8GBRAM/1TBHDD/1000Mbps cross-connected VLAN to Webserver However, with my setting on LiteSpeed , we still having some issue with load page. Problem: 1) The website getting slow when many concurrent users visited to the website (when reach 600-900 online members) 2) Load average server become high. (load average: 67.23, 60.45, 53.13) 3) LS Cache Hits : Low (still working on this issue) 4) Request Timeout Problem when huge user visit the website Here my current setting on LiteSpeed Quick Configuration of PHP suEXEC (Currently disabled) Quick Configuration of LiteSpeed Private Cache (Currently enabled) http://cl.ly/image/1q3L1B1L0f0r http://cl.ly/image/2F0U2E2g1q1I http://cl.ly/image/0S3p0Z3t0I1O http://cl.ly/image/1d2R2C1B1c07 http://cl.ly/image/1p1n0G1k0S0W http://cl.ly/image/2w0J0A2q2A3W http://cl.ly/image/0A0n1w2B073A Hope you can check my setting.
