    Must be something to this network bottleneck thing. I've gone mad and put up 8
    nodes on the Sabertooth. It's not even cracking a sweat, pushing an load average of 4.2

    So while thats lovely, individual node performance hasn't actually improved much. It has a bit... but nothing earth shattering. Now I've had trouble with the XFS nfs client wanting to connect to the same machine that the VM's are run
    on. Maybe there's some way to provide more caching for the bbs nfs share than I'm presently aware of. Opps just remembered with the load average so low, I can crank up the processor time alotted to each VM too.

    Most of the important stuff is already local to the VM its running in. The menus and screens, are on a local ram drive. The SBBS overlay is sitting in EMS. I can't think of anything much else to do. All the logs are on the NFS mount but that hardly seems worth worrying about.

    Are you running a DOS idler in each guest? (aka POWER.EXE i think

    Power is the DOS power management and yes thats running, they're also using TAME as well. In the past these made no difference in getting the load average
    under 1 for each VM though. 8VMs with an avg of 4 is unprecedented here.

    NFS tuning seems to be a rabbit warren in itself. I can't actually find any configs for it in boontu... but first stop was to find it and set it to tcp instead of udp, increase the number of threads available.

    Then came TCP tuning with a heavy suggestion to implement jumbo frames, which is s'posed to give up to a 33% improvement. Wonder if I should start taking notes on what I do now... ponder....

    if you are running Ubuntu, Debain ... # sudo apt-get install ethtool

    See this link ....

    Thanks for the pointer and info...

    There was/is a utility to do it. I remember using it under Linux
    to lock the NIC to the desired speed/duplex setting around 20 years

    The aforementioned ethtool will do it nicely. I don't think I've ever struck this particular oddity in Linux before, only with Win and with a right click here and a right click there, you do the hokey pokey and cross your teeth and hope its all fixed.

    I think I played with ethtool briefly when I first started messing around with wireless networks but thats only a vague memory tickling somewhere in the back of my head.
