Hello again, I was just getting frustrated after days of testing.
Hardware : Amd duron 1000, 512 mb scdram (133 mhz) udma100 disk. Running trustix secure linux 1.5. kernel 2.4.18 (however tests are the same with 2.2 kernels and 2.4.17) Yesterday i tested with mpm=worker settings: I've used default worker settings, then changed each and overy one of them but the problem remains : when the number of concurrent users exceeds (ThreadsPerChild +1) the number of requests per second drops drastically. (when concurrent users < ThreadsPerChild i get 1000 requests per second, if higher only 50 requests :( With mpm = prefork : apache 1.3.24 : ab -n 1000 -c 1 http://192.168.1.253/index.html Requests per second: 1040.58 [#/sec] (mean) Time per request: 0.96 [ms] (mean) Time per request: 0.96 [ms] (mean, across all concurrent requests) Transfer rate: 2328.82 [Kbytes/sec] received ab -n 10000 -c 500 http://192.168.1.253/index.html Requests per second: 940.82 [#/sec] (mean) Time per request: 531.45 [ms] (mean) Time per request: 1.06 [ms] (mean, across all concurrent requests) Transfer rate: 2114.40 [Kbytes/sec] received apache 2.0.35 ab -n 1000 -c 1 http://192.168.1.253/index.html Requests per second: 882.39 [#/sec] (mean) Time per request: 0.001 [ms] (mean) Time per request: 0.001 [ms] (mean, across all concurrent requests) Transfer rate: 1975.68 [Kbytes/sec] received ab -n 10000 -c 500 http://192.168.1.253/index.html Requests per second: 57.86 [#/sec] (mean) Time per request: 8.642 [ms] (mean) Time per request: 0.017 [ms] (mean, across all concurrent requests) Transfer rate: 129.56 [Kbytes/sec] received It seems like my apache doesnt start new processes fast enough. What am i doing wrong ?
