Inode cache tuning

Hi,

I have a number of servers replicating data with rsync. This generates
a lot of IO and I'm sure I can tune the system to perform better.

vmstat -s reports:
606116696253 total name lookups (cache hits 89%)

while kstat -n inode_cache reports:
maxsize 129534
maxsize reached 245984

I have a minimum of about 500MB RAM free

What do you suggest? Increasing ncsize, ufs_ninode? By how much?

Thanks,
Yonah
