Today I found that is good idea to increase this values also if
system is under the bigger filesystem activity e.g. cvs update. With
running cvs update system is slow in fs operations like directory
list. After increas of kern.maxvnodes to 65000 (i know this is
probably too much;) system worked smoothly again.
We should increase default kern.maxvnodes to something bigger than
45692 or at least document this somewhere so people can tune their
netbsd better. Is tunning netbsd chapter in our guide correct place ?
if yes I will write a patch .
