SVN 1.5.6 Performance Issues

Message I'm looking for some advice on troubleshooting my team's svn performance issues. Any recommendations on things I should look at would be greatly appreciated. Full details below.

Currently we have a VM hosted on an ESX 3.5 platform with 1vCPU and 4GB of RAM hosting a single repository for a large development group. The slice itself is running RHEL4 64bit and collabnet svn 1.5.6. It's supporting roughly 70 developers as well as automated builds via IBM's Build Forge product. The build machines are running the collabnet 1.5.6 client and our developers are using TortoiseSVN 1.5.9, Build 15518 - 32 Bit.

We've been running this setup without incident for over a year. Within the past few weeks we've started to see significant performance issues.

Examples are:

svn checkouts that normally take 3-4 minutes intermitantly take over 15 minutes.

SVN info normally takes seconds take over 7 minutes.

svn updates that normally take under a minute take over 10 minutes. Update set has been as small as 46kb when this occured.

A full review of the system resources haven't point to any constraints. Historical CPU trending shows no significant spikes. Memory utilization also seems ok with zero swap being used.
