[cvsnt] Re: CVSNT 2.0.58d CPU performance problems and the lockserver

Why do I have the feeling that this problem is being ignored by the CVSNT guru(s)?

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
