Indeed.

Yup. We have two RAID controllers on this machine. I just requested the system guys to install two new disks, RAID 0+1. We will put the CVSNT temp directory over there and see if it helps. I will let you know.

This may help us to determine whether it's the repository or the temp space that's the bottleneck.

I can't! I checked this performence tool, I have only a physical disk entry and C: and D: are grouped together, since it's the same array I guess.

Around 50 developers. 5-10 updates of the repository per day per developer. Around 3 commits per day per developer I would say. One cruise control, running every 24h. One Jira instance retrieving CVS logs every hours.
