Fabian,
As I don't know such a list, I just tell what i know. By the way, which
link layer technology are we talking about?
I'm primarily interested in 1-Gig Ethernet right now, though I'll need
to look at 10-Gig at some point.
For 1-GigEthernet my experience shows that the intel cards are working
quite well. You do not want to use cheaper ones like e.g. Netgear those at
least were not able to process a fully loaded link and then the driver
crashed. Sysconnect cards are as well working ok, though to as fast as the
intels. By the way you want to enable NAPI for Linux.
I've heard similar results on Intel.
I've found that interrupt coalescing makes a big difference in
throughput. In my application, I'm summarizing traffic at 100Msec
intervals. I'm not too concerned about the extra latency introduced by
the coalescing.
I'm putting together a simple benchmark program so I can get a better
understanding of various factors affecting performance.
The two metrics I looking at now are:
- What throughput can I get before seeing dropped packets
- CPU usage
All I do with the incoming packets is count bytes and packets.
I welcome any feedback on this.
For 10-GigEthernet i heard (no own experience) that the Neterion Cards are
good. Those are available in a special Solaris version as well.
I'll take a look at Neterion.
Thanks,
Andy
