For Sun systems, NFSv3 using 32kByte [rw]size over TCP has been the default configuration for 10+ years. Do you still see clients running NFSv2 over UDP? Note that an attribute-intensive NFS workload may be sync write bound, which means your attempts to improve network bandwidth efficiency will not be rewarded. OTOH, using an slog to a low-latency, nonvolatile write storage device will be rewarded. -- richard > In order to improve NFS client performance, it may be useful to > increase the 'rsize' and 'wsize' client mount options to 32K. > Solaris 10 defaults the buffer size to 32K but many other clients use > 8K.
