Server upgraded but still very poor performance!
Old setup:
Q9550 (4 threads) 8GB RAM RAID1 Web Frontend + MySQL 2CPU LSWS enterprise license New setup: Q9550 (4 threads) 8GB RAM RAID1 Dedicated MySQL server 2CPU LSWS enterprise license 3930K (12 threads) 32GB RAM RAID10 Dedicated Web Frontend server 2CPU LSWS enterprise license I am seeing barely any difference in performance increase. Example: Req/second about 90/second (Req in processing 400/second) This is nearly the same as the previous setup. How is this possible? Still takes 15-20 seconds to load the site despite the increased CPU. Disk I/O is under 5 at all times. And can LSWS staff give me the appropriate figures for the 32GB RAM server: Server: Memory I/O Buffer Tuning: Connection Timeout (secs) Max Keep-Alive Requests Keep-Alive Timeout (secs) Max Cached Small File Size (bytes) Total Small File Cache Size (bytes) Max MMAP File Size (bytes) Total MMAP Cache Size (bytes) AIO Block Size Max Request URL Length (bytes) Max Request Header Size (bytes) Max Request Body Size (bytes) Max Dynamic Response Header Size (bytes) Max Dynamic Response Body Size (bytes) Max Static File Size (bytes) Min Static File Size (bytes) Security: Static Requests/second Dynamic Requests/second Connection Soft Limit Connection Hard Limit Grace Period (sec) Banned Period (sec) Max CGI Instances Priority CPU Soft Limit (sec) CPU Hard Limit (sec) Memory Soft Limit (bytes) Memory Hard Limit (bytes) Process Soft Limit Process Hard Limit |

should figure out the bottle-neck of your server first. for those parameters, actually the default settings already being optimal. 32G memory will be fully utilized by OS as disk file cache. |
This is for any page of the site.
How can I increase Req/second? Does increasing Max CGI Instance help? I should not be seeing 100 Req/second (400 in processing) with this powerful server. On the old setup, I would see 100 Req/second (400 in processing) load is 40. New setup, I still see 100 Req/second (400 in processing) but load is 2. Although the load is low, the website still loading slow due to so many stuck in processing. What settings can be changed to increase the 100 Req/second to take full advantage of my server? |
can you paste "Real-Time Stats" here
|
I tracked down the issue to MySQL so now it seems to be running a lot better.
Please check my settings and realtime stats. I want to optimize for 2CPU license. This is for server with 3930K 6 physical core + 6 HT, 32GB RAM, dedicated web server. And I need to know how to whitelist certain IPs, I see this: Allowed List ALL I have many IP to whitelist, they keep getting blocked in anti-ddos until I raised the dynamic requests limit. I want to whitelist for example 39.219.89.139 and 172.89.11.235, please tell me exact lines I need to put. And the old setup/old server I don't need LSWS on it anymore since it is only MySQL server? http://s14.postimage.org/73x8ckvdd/realtime.gif http://s14.postimage.org/8o2kaz3rl/settings1.gif http://s9.postimage.org/6xuiiymsv/settings2.gif http://s18.postimage.org/jbsj4l9mh/settings3.gif http://s16.postimage.org/g3dhdxtr9/settings4.gif |

so it is ALL, 39.219.89.139T, 172.89.11.235T |

2. paste your lsphp5 ext app settings here. 3. increase Max CGI instance would NOT help. 4. php suEXEC set to 10 (good for most setup). increase it if you have very busy traffic (not in your case). |
I disabled that now and changed to 10000. Server only used for 1 website using exclusively CGI only. No PHP at all except the webmail/phpmyadmin. Is there anything else I can do for increasing req/sec? 2 CPU license is enough for this server or do I need more?

do you know how much traffic volume (req/sec) of your site is supposed to be? do your cgi scripts talk to database? is your database ok to handle the traffic? does your cgi script take a long time to finish? if web server is not the bottleneck (like in your case), no matter how fine tune it is, it would not make much difference.
