Without having a clue about your setup, I'll venture a guess. Others will probably give more specific SVN tips, but in my experience this sounds like it's related to IO. Several factors are involved; like raid-level, filesystem, svn database type, other activities on the server, etc. Check first which process' are contributing mostly to the load and also check the output from vmstat when this happens. You'd probably also want to mount the filesystem with 'noatime'.
