Hi all,
According to the file fs/nfsd/nfscache.c (line 30 on 2.6.23), reply 
cache is fixed size. Why is this a fixed size cache? Shouldn't be 
relative to the number of nfsd threads? I've a server with this statistics:

rc 0 959398 336415498

By what I've been researching this means: 0 hits, 959398 misses (I 
supose that means something like "recently deleted") and 336415498 not 
in cache (and never has been). Is that right?

Modifying the CACHESIZE to a bigger size do you think it could enhance 
NFS performance by getting some hits on the reply cache?

Thanks!
Jordi
