Message-ID: <47139B20.7070805@cesca.es> (raw)
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
