since I've got to switch a bunch of machines to 100Mbit ethernet, I'd like
to get an idea of stability/performance of different Ethernet Chipsets
supported by linux before bying a bunch of cards.
The card types available from our suppliers are:
* Dec Tulip (DC21*4*)
* 3com 3c905b/c
* Intel i82557/8/9
* Realtek 8129/8139
* VIA Rhine (VT86C100A and 3043)
>From reading the comments in the drivers:
Intel: Complex hardware ("The Speedo3 is very similar to other Intel
network chips, that is to say
"apparently designed on a different planet""). Don't know about
performance/stability but this comment doesn't sound very reassuring.
Realtek: works, but lousy hardware, low cost, low performance. I've had
stability problems using these.
Via-rhine: works reliably here, hardware limitations make zero-copying
impossible (alignment requirements for buffers). So, performance shouldn't
be too good but then teh cards are very cheap.
3com: No personal experience - from the driver source, these seem to be
rather nice.
Dec Tulip: No personal experience - from the driver source, these seem to
be rather nice.
Now I'd be interested if anyone has hard data (benchmarks) on performance
of these chipsets under linux, and if there are known stability or
reliability issues with any of them.
Bye, Martin
