Note that this My smp alpha box drives a single tulip over 12MB/sec in full duplex using tcp without any problem at all. So I definitely cannot reproduce. You may want to try to reproduce with 2.4.5pre6aa1 btw. If you've not tried it yet you can consider also using egcs 1.1.2 as compiler just in case. You may also want to keep an eye on the VM, on alpha I see very weird things happening. Andrea
