Hi, I read this article: http://mongrel.rubyforge.org/docs/how_many_mongrels.html and decided to play around a little bit..
I didn't test it on mongrel, but on a Nginx (on a default page saying "Welcome to nginx").. just to get the feel for the numbers.. I'm using Slicehost VPS with 256 MB RAM.. Here are the results: $ time httperf --server www.server.com --port 80 --num-conns 25 httperf --client=0/1 --server=unebo --port=80 --uri=/ --send-buffer=4096 --recv-buffer=16384 --num-conns=25 --num-calls=1 Maximum connect burst length: 1 Total: connections 25 requests 25 replies 25 test-duration 10.048 s Connection rate: 2.5 conn/s (401.9 ms/conn, <=1 concurrent connections) Connection time [ms]: min 362.1 avg 401.9 max 451.5 median 402.5 stddev 15.4 Connection time [ms]: connect 204.2 Connection length [replies/conn]: 1.000 Request rate: 2.5 req/s (401.9 ms/req) Request size [B]: 56.0 Reply rate [replies/s]: min 2.4 avg 2.4 max 2.4 stddev 0.0 (2 samples) Reply time [ms]: response 197.6 transfer 0.1 Reply size [B]: header 216.0 content 151.0 footer 0.0 (total 367.0) Reply status: 1xx=0 2xx=25 3xx=0 4xx=0 5xx=0 CPU time [s]: user 0.53 system 9.00 (user 5.3% system 89.6% total 94.9%) Net I/O: 1.0 KB/s (0.0*10^6 bps) Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0 Errors: fd-unavail 0 addrunavail 0 ftab-full 0 other 0 real 0m10.059s user 0m0.528s sys 0m9.013s $ time httperf --server www.server.com --port 80 --num-conns 25 --rate 2.5 httperf --client=0/1 --server=unebo --port=80 --uri=/ --rate=2.5 --send-buffer=4096 --recv-buffer=16384 --num-conns=25 --num-calls=1 Maximum connect burst length: 1 Total: connections 25 requests 25 replies 25 test-duration 10.005 s Connection rate: 2.5 conn/s (400.2 ms/conn, <=3 concurrent connections) Connection time [ms]: min 323.6 avg 411.9 max 822.9 median 394.5 stddev 90.9 Connection time [ms]: connect 214.4 Connection length [replies/conn]: 1.000 Request rate: 2.5 req/s (400.2 ms/req) Request size [B]: 56.0 Reply rate [replies/s]: min 2.4 avg 2.4 max 2.4 stddev 0.0 (2 samples) Reply time [ms]: response 197.5 transfer 0.1 Reply size [B]: header 216.0 content 151.0 footer 0.0 (total 367.0) Reply status: 1xx=0 2xx=25 3xx=0 4xx=0 5xx=0 CPU time [s]: user 0.46 system 7.59 (user 4.6% system 75.9% total 80.4%) Net I/O: 1.0 KB/s (0.0*10^6 bps) Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0 Errors: fd-unavail 0 addrunavail 0 ftab-full 0 other 0 real 0m10.014s user 0m0.456s sys 0m7.596s Since the article said "start with 100", I'm a little bit 'worried', because I hit 10s with only 25 connections.. Is this normal? Can someone make more sense out of this so we can make a fruitful discussion out of it? I'm really interested in understanding more about the topic.
