I know.. I know... Simple benchmarks mean nothing but I couldn't help playing with the new(ish) mod_wsgi module for my favorite webserver Nginx.
Nginx: http://nginx.net/ Nginx mod_wsgi module: http://wiki.codemongers.com/NginxNgxWSGIModule I tested Nginx vs. the recommended setup of Lighttpd/Fastcgi. These very simple and flawed tests were run on Debian Etch running under virtualization (Parallels) on my Macbook Pro. Hey I said they were flawed.. :-) The results show Nginx/WSGI performing 3x as fast as Lighttpd/Fastcgi, over 1000 requests per second!! I tested both with Keep-Alives on and off. I'm not sure why Nginx/WSGI performed 2x as fast with keep-alives on. *********** Full results below ************* -------------------------------------------- Nginx 0.5.34 - Keepalives On --------------------------------------------- ab -c 10 -n 1000 -k http://10.211.55.4/wsgi-webpy/david This is ApacheBench, Version 1.3d <$Revision: 1.73 $> apache-1.3 Server Software: nginx/ 0.5.34 Server Hostname: 10.211.55.4 Server Port: 80 Document Path: /wsgi-webpy/david Document Length: 14 bytes Concurrency Level: 10 Time taken for tests: 0.970 seconds Complete requests: 1000 Failed requests: 0 Broken pipe errors: 0 Keep-Alive requests: 1001 Total transferred: 136136 bytes HTML transferred: 14014 bytes ** Requests per second: 1030.93 [#/sec] (mean) ** Time per request: 9.70 [ms] (mean) Time per request: 0.97 [ms] (mean, across all concurrent requests) Transfer rate: 140.35 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.4 0 5 Processing: 1 9 4.3 9 26 Waiting: 0 9 4.2 9 25 Total: 1 9 4.3 9 26 Percentage of the requests served within a certain time (ms) 50% 9 66% 11 75% 12 80% 13 90% 15 95% 17 98% 20 99% 22 100% 26 (last request) -------------------------------------------- Nginx 0.5.34 - No Keepalives --------------------------------------------- ab -c 10 -n 1000 http://10.211.55.4/wsgi-webpy/david This is ApacheBench, Version 1.3d <$Revision: 1.73 $> apache-1.3 Server Software: nginx/ 0.5.34 Server Hostname: 10.211.55.4 Server Port: 80 Document Path: /wsgi-webpy/david Document Length: 14 bytes Concurrency Level: 10 Time taken for tests: 2.378 seconds Complete requests: 1000 Failed requests: 0 Broken pipe errors: 0 Total transferred: 131131 bytes HTML transferred: 14014 bytes ** Requests per second: 420.52 [#/sec] (mean) ** Time per request: 23.78 [ms] (mean) Time per request: 2.38 [ms] (mean, across all concurrent requests) Transfer rate: 55.14 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect: 0 4 2.9 3 26 Processing: 8 19 8.8 18 136 Waiting: 0 19 8.8 17 135 Total: 8 23 8.9 21 142 Percentage of the requests served within a certain time (ms) 50% 21 66% 24 75% 26 80% 28 90% 34 95% 40 98% 45 99% 47 100% 142 (last request) ********************************************************************* -------------------------------------------- Lighttpd 1.4.13 - Keepalives On --------------------------------------------- ab -c 10 -n 1000 -k http://10.211.55.4/david This is ApacheBench, Version 1.3d <$Revision: 1.73 $> apache-1.3 Server Software: lighttpd/ 1.4.13 Server Hostname: 10.211.55.4 Server Port: 80 Document Path: /david Document Length: 14 bytes Concurrency Level: 10 Time taken for tests: 2.901 seconds Complete requests: 1000 Failed requests: 1 (Connect: 0, Length: 1, Exceptions: 0) Broken pipe errors: 0 Keep-Alive requests: 942 Total transferred: 138711 bytes HTML transferred: 14001 bytes ** Requests per second: 344.71 [#/sec] (mean) ** Time per request: 29.01 [ms] (mean) Time per request: 2.90 [ms] (mean, across all concurrent requests) Transfer rate: 47.81 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect: 0 0 1.1 0 21 Processing: 3 28 29.3 22 385 Waiting: 3 28 29.3 22 385 Total: 3 28 29.3 22 385 Percentage of the requests served within a certain time (ms) 50% 22 66% 26 75% 31 80% 34 90% 48 95% 60 98% 100 99% 164 100% 385 (last request) -------------------------------------------- Lighttpd 1.4.13 - No Keepalives --------------------------------------------- ab -c 10 -n 1000 http://10.211.55.4/david This is ApacheBench, Version 1.3d <$Revision: 1.73 $> apache-1.3 Server Software: lighttpd/ 1.4.13 Server Hostname: 10.211.55.4 Server Port: 80 Document Path: /david Document Length: 14 bytes Concurrency Level: 10 Time taken for tests: 4.017 seconds Complete requests: 1000 Failed requests: 1 (Connect: 0, Length: 1, Exceptions: 0) Broken pipe errors: 0 Total transferred: 134269 bytes HTML transferred: 14029 bytes ** Requests per second: 248.94 [#/sec] (mean) ** Time per request: 40.17 [ms] (mean) Time per request: 4.02 [ms] (mean, across all concurrent requests) Transfer rate: 33.43 [Kbytes/sec] received Connnection Times (ms) min mean[+/-sd] median max Connect: 0 3 4.9 2 68 Processing: 3 36 49.6 28 852 Waiting: 2 35 49.6 28 852 Total: 3 39 50.1 30 855 Percentage of the requests served within a certain time (ms) 50% 30 66% 36 75% 41 80% 44 90% 61 95% 87 98% 148 99% 252 100% 855 (last request) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "web.py" group.
