[ http://issues.apache.org/jira/browse/DIRMINA-232?page=comments#action_12424953 ] Niklas Therning commented on DIRMINA-232: -----------------------------------------
Emmanuel suggested that the poor performance might be due to nagle which I indeed think is the case. Here's the result with nagle disabled: [EMAIL PROTECTED]:~$ ab2 -k -n 100 http://localhost:8080/index.html This is ApacheBench, Version 2.0.41-dev <$Revision: 1.141 $> apache-2.0 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 1998-2002 The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient).....done Server Software: MINA Server Hostname: localhost Server Port: 8080 Document Path: /index.html Document Length: 10000 bytes Concurrency Level: 1 Time taken for tests: 0.107275 seconds Complete requests: 100 Failed requests: 0 Write errors: 0 Keep-Alive requests: 100 Total transferred: 1011400 bytes HTML transferred: 1000000 bytes Requests per second: 932.18 [#/sec] (mean) Time per request: 1.073 [ms] (mean) Time per request: 1.073 [ms] (mean, across all concurrent requests) Transfer rate: 9200.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.0 0 0 Processing: 0 0 3.3 0 32 Waiting: 0 0 3.3 0 32 Total: 0 0 3.3 0 32 Percentage of the requests served within a certain time (ms) 50% 0 66% 0 75% 0 80% 0 90% 0 95% 1 98% 6 99% 32 100% 32 (longest request) Add the following to Main.java before the bind call to disable nagle: ( ( SocketSessionConfig ) ( config.getSessionConfig() ) ).setTcpNoDelay( true ); Thanks Emmanuel for pointing this out! What do you think Oleg, can we close this issue? > Performance of StreamIoHandler degrades dramatically when the IoSession is > kept alive between HTTP requests > ----------------------------------------------------------------------------------------------------------- > > Key: DIRMINA-232 > URL: http://issues.apache.org/jira/browse/DIRMINA-232 > Project: Directory MINA > Issue Type: Bug > Affects Versions: 0.9.5 > Environment: Ubuntu Linux 6.06 > Reporter: Oleg Kalnichevski > > I have been observing a strange issue with MINA's StreamIoHandler while > benchmarking the performance of the HTTP server based on HttpCore and MINA. > The throughput of the StreamIoHandler tends to degrade dramatically when the > IoSession is kept alive between HTTP requests. The problem is perfectly > reproducible with a slightly modified version of HttpProtocolHandler that > ships with MINA (no external code is involved). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
