Subject Re: HttpClient performance (with download URL)
Date Fri, 20 Aug 2004 08:09:25 GMT
Zulfi,

I ran the profiler on
HttpClient 2.0-alpha3 and
HttpClient 2.0 Branch latest CVS

I basically used Oleg's test case provided in the email thread you
mentioned (code included).
I turned off logging and stale connection checking. I ran the tests
against a local Tomcat on a Win2k Pro workstation with JDK 1.4.2_02 in
Eclipse 3.0.

The profiler used was:
http://eclipsecolorer.sourceforge.net/index_profiler.html

Feel free to discuss the results. Results are available for 7 days at:

ftp://ftp.nose.ch/pub/outgoing/httpclient/profiling.zip
