Re: best NIC Speed + Gbit Q
Hi, but i now change some Servers from SuSE to debian and now is the best time to get them a good nic. What about a Gigabit NIC ? I am setting up a new RAID file server that will see some traffic. My spec is to us a Gigabit NIC on a standard (32 bit) PCI card. I will be talking to 100Mbit clients. (so will not use special Gbit tricks i.e. jumbo-frame) I do think there is no server performance penalty when using a 1Gig NIC, possibly benefits. The server would probably be literally interrupt driven under heavy load, what with the RAID and fast the NIC. But that would only apply when it is going well beond the limitations of a 100 Mbit card. I know it will not deliver 10 times 100Mbits because of overhead and interrupt load but I would like to see it max at more than 300Mbit. Some CPU offloading to the NIC would be cool. Who much extra memory would help performance? As the price is comming down I hope to move to installing only 1Gig NICs on all new system. Comments, links ?? Re. 100MBit cards. Most of my servers are NOT using much transfer bandwith (behind a 10Mbit connection to the net). I use 100Mbit full-duplex on all new systems, Most important for me is time to get things working and stability, I like: Driver on the Linux install disk Autoprobe with no parameters to the module Duplex Auto_Negotiation that works :-) (If a card (type that I know) does not work when I install a new system I throw in the bin (trash)). The cards I like and have worked well for me are: 3C905, sold second hand for almost nothing Realtek RTL-8139, have had no problems with them INTEL Ether Pro 100, not many but work ok normally i use the 8139 becaue the work everywhere. I am happy to report success when having to clamp to 10Mbit full-duplex using this card.

I am not sure the problem is the cpu processing packets. The 2 mains bottle necks are the bus and the interrupt lacency. the people of the click router project (www.pdos.lcs.mit.edu/click/) made some studdies about those limitation (paper is quite interesting). Their solution is to use DMA based drivers (they coded, tested and modified some of the card drivers, have a look for more details). That's why i dont think that card cpu offloading is not an immediate solution (off course it'll help). Re. 100MBit cards.

Re: best NIC Speed
I double checked with the sysadmin who had problems with 3Com Cards (once and then) spontaneously sending broadcast when the card turns old. He says, it is not Windows specific, but happens on Linux too and he once read some article where 3Com confirmed the problem - however: no reference given.

Re: best NIC Speed
i agree, but not specially for the hardware quality of the Pro/X intel card serie, but for the quality of the driver which have been developed by intel and give out very good perf. The core issue is the driver and not the hardware in a lot of cases. Finally, the hardware offload for ipsec and others is something which is looked at but the kernel guys (this should be part of a whole frameword handeling ipsec offload and hardware crypto card in linux, for more info, Documentation/crypto).

Re: best NIC Speed
Yes intel nic are the best for 10/100 based lan. Some of the Pro100+ Card also have the problem - if the network equipment (switch) is powered off and on the card is light-up on half-duplex. Some old intel nic-s have transeever bug but in new in 2.4 kernels this is fixed on software level. for 3com nic's i have good word's too. there is 3com 10/100 For Complete PC Managment nic that is designed for performance, hi network load and low cpu ussage. If you by 3com card look their revision, do not take cards with B rev. they are old and have some low performace tips.
