Slow NFS

[raymond.meyer%rambler.ru@localhost]

Hi, I have two machines running NetBSD-5 beta, one i386 - NFS server, other 
sparc64 - NFS client. For some reason NFS is very slow, i.e. if I 
mount /opt/pkgsrc via NFS and then do something like:

cd /opt/pkgsrc
find .

then it seems to block, i.e. each entry printed by find takes about 10 seconds 
or longer to appear on the screen. Something is very wrong with this. Any 
ideas what it might be?
