I've got an Alpha workstation running 5.1. It's got a tulip-based 10/100
card in it, running at 100Mb, half-duplex. Downloading (ftp or smb) from
this machine I get speeds in excess of 1000KB/s. However, uploading to it,
I get around 150KB/s (same results from multiple machines). I've replaced
cables and used a different switch port, but still the problem persists.
The only issue I can find is in the messages file:
Jan 31 07:39:19 mojo vmunix: tu0: transmit FIFO underflow: threshold raised
to: 256 bytes
Jan 31 07:39:41 mojo vmunix: tu0: transmit FIFO underflow: threshold raised
to: 512 bytes
Jan 31 07:52:26 mojo vmunix: tu0: transmit FIFO underflow: threshold raised
to: 1024 bytes
Although I don't really know if that's a problem, per se. Does anyone have
any suggestions on what might cause this? I don't have another NIC to try
right now, but if I can prove it's a bad NIC, I'll got out and buy another
one.
