Hello, I'm running simple benchmark, ab (freebsd) -> apache 1.3.37 (freebsd) and ab (freebsd) -> apache 1.3.34 (linux) I do not pretend that the benchmark is accurate :) and do not really care about results in linux, but they are here just for comparison. ab -t 30 -c 100 http://boar.cmotd.com:81/manual/ (boar is freebsd) Finished 26678 requests Server Software: Apache/1.3.37 Server Hostname: boar.cmotd.com Server Port: 81 Document Path: /manual/ Document Length: 9364 bytes Concurrency Level: 100 Time taken for tests: 30.000 seconds Complete requests: 26678 Failed requests: 0 Broken pipe errors: 0 Total transferred: 260937758 bytes HTML transferred: 249863898 bytes Requests per second: 889.27 [#/sec] (mean) Time per request: 112.45 [ms] (mean) Time per request: 1.12 [ms] (mean, across all concurrent requests) Transfer rate: 8697.93 [Kbytes/sec] received And this is what I have when the host is linux (some version of ubuntu not tunned just base install) ab -t 30 -c 100 http://dany.cmotd.com:80/manual/ Server Software: Apache/1.3.34 Server Hostname: dany.cmotd.com Server Port: 80 Document Path: /manual/ Document Length: 9158 bytes Concurrency Level: 100 Time taken for tests: 30.000 seconds Complete requests: 32848 Failed requests: 0 Broken pipe errors: 0 Total transferred: 309841821 bytes HTML transferred: 300932967 bytes Requests per second: 1094.93 [#/sec] (mean) Time per request: 91.33 [ms] (mean) Time per request: 0.91 [ms] (mean, across all concurrent requests) Transfer rate: 10328.06 [Kbytes/sec] received changing "-c" from 100 to 500 doesn't show big difference in final results. What can I do to improve my freebsd web server ? cat /etc/sysctl.conf kern.fallback_elf_brand=3 net.inet.ip.random_id=1 (I changed this 0, but nothing changed) kern.maxfiles=25000 net.inet.tcp.delayed_ack=0 net.inet.tcp.inflight.enable: 0 (0/1 does not make difference) CPU: AMD Athlon(tm) 64 Processor 3200+ (2002.57-MHz K8-class CPU) FreeBSD 6.2-STABLE amd64 both httpd.conf have: MinSpareServers 10 MaxSpareServers 20 MaxClients 500 MaxRequestsPerChild 0 StartServers 10 And yes I know "StartServers 10" is not optimal for benchmarking, but this is not the problem. I also found that increasing kern.ipc.maxsockets to 16384+ give a boost and "completed requests" jump to: 28067 but it is still not 32K :) Increasing kern.ipc.nmbclusters doesn't change the picture at all. What else I can change/test to improve performance? -- Best Wishes, Stefan Lambrev ICQ# 24134177
