I did a little test using the apache benchmarking tool (sudo apt-get install apache2-utils): This one does 100 requests with at most 10 concurrent requests. timli...@timvaio:/usr/lib/cgi-bin/world$ ab -n 100 -c 10 "http://localhost/cgi-bin/world/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=-36.215710,6.817432,-9.700450,58.551008&CRS=EPSG:4326&WIDTH=1077&HEIGHT=552&LAYERS=Continent,Country,Cities&STYLES=,,&FORMAT=image/jpeg&DPI=96"; This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient).....done Server Software: Apache/2.2.14 Server Hostname: localhost Server Port: 80 Document Path: /cgi-bin/world/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=-36.215710,6.817432,-9.700450,58.551008&CRS=EPSG:4326&WIDTH=1077&HEIGHT=552&LAYERS=Continent,Country,Cities&STYLES=,,&FORMAT=image/jpeg&DPI=96 Document Length: 49558 bytes Concurrency Level: 10 Time taken for tests: 39.587 seconds Complete requests: 100 Failed requests: 0 Write errors: 0 Total transferred: 4971400 bytes HTML transferred: 4955800 bytes Requests per second: 2.53 [#/sec] (mean) Time per request: 3958.659 [ms] (mean) Time per request: 395.866 [ms] (mean, across all concurrent requests) Transfer rate: 122.64 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 1 2.3 0 13 Processing: 3411 3930 155.7 3946 4221 Waiting: 3382 3824 140.6 3836 4110 Total: 3411 3931 155.7 3946 4221 Percentage of the requests served within a certain time (ms) 50% 3946 66% 3991 75% 4016 80% 4050 90% 4106 95% 4150 98% 4212 99% 4221 100% 4221 (longest request) It seems to cope ok with a number of concurrent users. A bit of tilecache in front of it may speed things up for timing sensitive folks (also not running it on my laptop might make it faster :-) ) Regards Tim -- Tim Sutton - QGIS Project Steering Committee Member (Release Manager) ============================================== Please do not email me off-list with technical support questions.
