NIC chipsets	by ripley8	2003-02-01 04:14:42
I just wondered whether $15 was cheap or expensive in comparison to the EUR 8 I paid. And yes, chipset can matter a lot. See the comments on top of if_rl.c (the RealTek driver source of FreeBSD) about how great a design they are. For my use at home they're fine, but don't even think about a RTL8139 chip for a heavily loaded server where you want to spare every cpu cycle you can for the services themselves. It's kinda like SCSI drives compared to IDE. You really do see a performance difference with command queueing etc. We recently reorganized the disk configuration of the news cache server at IN-Berlin to have the spool on a striped raid and the load dropped from steady 5 to below 2. Now imagine you had a big router with more than 5 interfaces and the cpu greeting every packet on any of these interfaces and copying them around itself.
