| // bench.c: invoke Apache Benchmark (ab) for a concurrency range and collect | ||
| // results in a file suitable for OpenOffice.org SpreadSheet charting | ||
| // | ||
| // 100.html is a 100-byte file initially designed to avoid testing the | ||
| // kernel (I wanted to compare the CPU efficiency of each Web server). | ||
| // | ||
| // The ITER define can be set to 1 to speed up a test but in that case | ||
| // values are not as reliable as when using more rounds (and using a | ||
| // low ITER[ations] value usually gives lower performances). | ||
| // | ||
| // G-WAN for Windows upgrades Registry system values to remove some | ||
| // artificial limits (original values are just renamed), you need to | ||
| // reboot after you run G-WAN for the first time to load those values. | ||
| // Rebooting for each test has an effect on Windows (you are faster), | ||
| // like testing after IIS 7.0 was tested (you are even faster), and | ||
| // the Windows Vista 64-bit TCP/IP stack is 10% faster (for all) if | ||
| // ASP.Net is *not* installed. | ||
| // | ||
| // Linux Ubuntu 8.1 did not show those boot-related side-effects but | ||
| // here also I have had to tune the system to run the test: | ||
| // | ||
| // sudo gedit /etc/security/limits.conf | ||
| // * soft nofile = 200000 | ||
| // * hard nofile = 200000 | ||
| // | ||
| // sudo gedit /etc/sysctl.conf | ||
| // fs.file-max = 200000 | ||
| // net.ipv4.ip_local_port_range = 1024 65535 | ||
| // net.ipv4.ip_forward = 0 | ||
| // net.ipv4.conf.default.rp_filter = 1 | ||
| // kernel.sysrq = 0 | ||
| // net.core.rmem_max = 262143 | ||
| // net.core.rmem_default = 262143 | ||
| // net.ipv4.tcp_rmem = 4096 131072 262143 | ||
| // net.ipv4.tcp_wmem = 4096 131072 262143 | ||
| // net.ipv4.tcp_sack = 0 | ||
| // net.ipv4.tcp_timestamps = 0 | ||
| // kernel.shmmax = 67108864 | ||
| // | ||
| // As I was not able to make the 'open files limit' persist for G-WAN | ||
| // after a reboot G-WAN attemps to setup this to an 'optimal' value | ||
| // depending on the amount of RAM available on your system: | ||
| // | ||
| // fd_max=(256*(tram/4)<200000)?256*(tram/4):1000000; | ||
| // | ||
| // Other values may need to be tuned to get optimal Linux performances | ||
| // I just did my best as a one-month Linux newbe. | ||
| // | ||
| // NB: this test was 15-20% faster (for all) when ab was running on a | ||
| // computer and the Web server on another machine via a gigabit | ||
| // LAN (but absolute performances were less interesting me than | ||
| // relative performances). | ||
| // | ||
| // This program is left in the public domain | ||
