    [PATCH] Lift the 256 outstanding NFS read/write request limit. · 0288cf54
    Trond Myklebust authored
    Given the previous set of patches that integrate NFS with the VM +
    pdflush memory control, and add mechanisms to cope with low memory
    conditions, the time is now ripe to rip out the 256 outstanding
    request limit, as well as the associated LRU list in the superblock,
    and the nfs_flushd daemon.
    
    The following patch offers a 30% speed increase on my test setup with
    512MB of core memory (iozone using 4 threads each writing a 512MB file
    over 100Mbit to a Solaris server). Setting mem=64m, I still see a 2-3%
    speed increase.
