    LX3 - Network transfer speed issue

    I do seem to have network transfer speed issue with LX3. What kind of speeds others are getting with it?
    LX3 over gbit network with NFS:

    Code:
    Results for write throughput:
    97.612 Mbit/s with udp,async,wsize=8192
    97.612 Mbit/s with tcp,async,wsize=8192
    97.612 Mbit/s with tcp,async,wsize=32768
    97.612 Mbit/s with tcp,async,wsize=16384

    89.478 Mbit/s with tcp,async,wsize=4096

    Results for read throughput:
    1073.741 Mbit/s with udp,async,rsize=8192
    1073.741 Mbit/s with udp,async,rsize=32768
    1073.741 Mbit/s with udp,async,rsize=16384
    1073.741 Mbit/s with tcp,async,rsize=8192
    1073.741 Mbit/s with tcp,async,rsize=4096
    1073.741 Mbit/s with tcp,async,rsize=32768
    1073.741 Mbit/s with tcp,async,rsize=16384
    To the same server but with other machine, so server not limiting write throughput

    Code:

    Tested now with several different images from different ages and this is the best result

    Code:
    root@xpeedlx3:~# dd if=/dev/zero of=/home/root/temp/testfile bs=512k count=1000
    
    1000+0 records in
    1000+0 records out
    524288000 bytes (500.0MB) copied, 45.118345 seconds, 11.1MB/s
