Hi all,
after having installed http egg,
I've built the http-server sample I've found at the page
http://www.call-with-current-continuation.org/eggs/http.html
Now I'm testing it using Apache benchmark ab,
in a test run like this:
ab -n 1000 -c 10 http://localhost:4242/index.html
(1000 requests for 10 concurrent users)
I take the result
Time taken for tests: 4.760289 seconds
Complete requests: 1000
Failed requests: 0
Write errors: 0
Total transferred: 111000 bytes
HTML transferred: 23000 bytes
Requests per second: 210.07 [#/sec] (mean)
Time per request: 47.603 [ms] (mean)
Time per request: 4.760 [ms] (mean, across all concurrent requests)
Transfer rate: 22.69 [Kbytes/sec] received
That is not too bad, consider my box is a
Intel4 CPU2.60GHz (under Gnu/Linux, bogomips: 5111.80)
The problem is that this benchmark run broke the server,
after having completed the run, *the server dies with
a "broken pipe" message*.
I was able to reproduce this with both 1.63 and 1.66
under Gnu/Linux FC2 and MacOSX 10.3.5.
Any idea how to fix this ? With only 2 concurrent users
I take the same problem.
Regards
/gp
