Even with the AV turned off on the repository directory and the reverse DNS lookup disabled the performance hit after 4 or more cvs.exe processes run on the server the CPU is pegged at close to 98 to 100%. WE tried upgrading to a better machine with a dual, multi-threaded Pentium 4 processor. With up to 10 cvs.exe processes running on the machine the CPU is at 85% but the majority of the CPU is held up by the lockserver process. I find it hard to believe that CVSNT server can only support less then 10 concurrent users at one time. I have scoured the internet for possible performance issues but there is not much out there. Anyone else running into this issue? Any help would be greatly appreciated, thanks


I've seen this thread and we do have the same problem running CVSNT 2.0.51d. AV is not the issue here since we monitor disk activites and idle time is almost 100%. The locking service is consuming 50% with an HT processor (I assume it's 100% in this case). A single checkout is *very* slow (only one CVS session).

So what's wrong here? Upgrading is not an option: last time I tried, some files from our repository dissapeared.

Thanks,
Stéphane
