Hello, Eric! You wrote to "Oleg Gawriloff" <bar...@telecom.by> on Wed, 20 Oct 2004 08:08:32 -0500:
EA> I've had really great performance with the em NICs, and bad experiences EA> with bge's (the hardware is flaky). OK, we'll try. Is there any problems with any of supported chipsets in em-driver with polling? There many negative answer about polling support in fxp on 82550, and good answers about 82558 and 82559 with fxp-driver.

We use only one NIC, with five 802.1q vlan sub-interfaces configured. Is there any ideas how can I diagnose bottlenecks on bus?
With best regards, Oleg Gawriloff.
