We've done > worse ;) That scp test shows 50%ish - but that was a quickie. The VNC client even reported a 719Kbps throughput down from the more usual 11500Kbps it starts off with. The first scp I tried when the sluggishness was intolerable was going at 200KB/s - which shows the problem can easily get in the neighborhood of an order of magnitude. Thanks, --alessandro "Dreamer ?
