I am able to achieve the write speeds here (near wire speed) but am getting between 30-50MB/s when reading with bonnie++ on the NFS client. I have been through every nfs and tcp tweak fathomable (have tried udp as well). The NFS server's OS can easily read +200MB/s however this is not being translated to the NFS client. ideas or things to check?
On a side note, under TCP i'm noticing the NFS server's tcp window is being advertised lower than a single MTU (always 501 bytes or lower), this seems related but no amount of TCP tweaking could increase this. both the client and host are CentOS 5 x86_64.
