I'm building Linux-based routers and need to be able to forward as many packets per second as possible over gigabit ethernet. It turns out that choice of network adaptor is critical, but very little information is available from manufacturers or on the web about packets-per-second performance of different cards. Here's a web page summarizing what I've learned, mostly about the Intel Pro/1000 card:
http://www.pdos.lcs.mit.edu/~rtm/e1000/
The short version is that the Intel Pro/1000 seems to be a lot faster than the Alteon Tigon-II or the SysKonnect card for small (60-byte) packets. The Intel card can send or receive at least 500,000 60-byte packets per second (about 1/3 of a gigabit/second). On the other hand, the Intel Linux driver requires a lot of hacking to achieve that rate; with the unmodified driver the board is about half that fast. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
