sys/nfs nfs_serv.c
Log:
Add a readahead heuristic to the NFS server side code. While the server
cannot unilaterally pass data to a client it can reduce the physical
disk transaction overhead by reading larger blocks. This results in
better pipelining of requests/responses over the network and an almost
100% increase in cpu efficiency on the server. On a 100BaseTX network
NFS read performance increases from 8.5 MBytes/sec to 10 MB/sec (maxed
out), and cpu efficiency increases from 72% idle to 80% idle on the server.
