I know this has been mentioned already, but have you tried increasing your
kern.maxvnodes with sysctl? I was experiencing similar issues on this Dell I8K
(5400 RPM IDE drive, 512 MB RAM) with the default maxvnodes of 17191. I first

68764 and it does seem even better now. Doing a cvs update with multiple
