Community technical support mailing list was retired 2010 and replaced with a professional technical support team. For assistance please contact: Pre-sales Technical support via email to sales@march-hare.com.

Firstly, please note that it is not my intention to criticise CVSNT, nor
to start a religious debate - I simply have a problem that I need to
solve and would appreciate the group's assistance. 

I'm having trouble getting the performance our developers require out
of our installation of CVSNT, and my testing has shown it to be
considerably slower for comprable hardware than CVS on other platforms.
I have tested CVSNT on Windows 2000 (some Advanced Server, some
Professional) with various hardware against CVS 1.11 on Linux and
Solaris.  Testing was against a module containing 700 files in 170
directories, the vast majority of which are Java and related source
files. The test I chose was a repeated update from WinCVS Beta
10 Build 1 on a stable source tree (ie: no actual updates resulted). 

Here are the results I got (there are several runs for some

Hardware                Time        CVS version                  OS
PIII 1.1GHz, 1Gb        3:38        CVSNT Build 57i     Win2k
(current server)        3:30 

P4 1.4GHz, 512Mb        1:35        CVSNT Build 57i     Win2k
                        1:02        CVSNT Build 65 

P4 2.4GHz, 512Mb        0:22        CVSNT Build 65      Win2k

PIII 0.8GHz, 512Mb      0:18        CVS 1.11                     Linux
2.4.2-2 (Redhat) 

Sun E250, dual 400MHz   0:03        CVS 1.11 			 Solaris

Comparing the PIII's running Win2k (1.1GHz) and Linux (0.8GHz) would
suggest the Linux version is an order of magnitude faster for given
hardware.  Are these results typical?  Is there anything we can do to
improve performance on Win2k?  Obviously we could move the service to a
faster server, but this would either cost money or cause operational

Thanks for your assistance.
