I have a server with 4 em(4) cards in it: two are on-board PCIe, and two are
on a single PCIe expansion card. The on-board NICs are Intel 82573E and
82573L chipsets (one of each), while the expansion card has two 82571EB
ports.
Recently I've been trying to increase throughput on this box (we use it as a
firewall). I have taken some time to upgrade the OS, try different rulesets,
and make other tweaks. Many of those items have helped, but there is one
speed issue I haven't been able to resolve.
The two internal cards (82673 chipset) don't seem to be able to pass traffic
at a rate greater than 670 Mbits/s. If I forward traffic on the other two
cards (the 82571EB chipset), I get "line rate" 941Mbits/s. I'm testing with
two directly-attached machines running benchmark tools (ttcp, iperf, netperf).
670Mbits/s is the best I can do, and that's with pf disabled (raw forwarding),
no VLAN tagging or other features enabled. I'm testing under 5.1-RELEASE
right now (currently booted under i386 GENERIC SP, but I've tried amd64 and MP
as well with no changes).
I've toyed around a fair amount with different settings, and I even rolled my
own kernel this morning to comment out some crufty "workaround" code in the
em(4) driver that targets this chipset. However, nothing has made a
difference in the rate I can achieve. There are no ierrs, ifq drops, or other
issues reported by the system; the card just seems to max out at 670.
I also booted the box with Debian Linux, and was able to get 941 Mbits/s on
these cards without any tweaking necessary. Therefore, I suspect it's a
driver issue in the OpenBSD code that's preventing this chipset from reaching
it's full potential.
Are there any obvious steps that I'm missing, or can anyone verify that some
em(4) chipsets are known to have performance issues under OpenBSD? At this
point I'm more curious than anything else. I'll use the faster 82571 cards
for forwarding and keep the on-board ports for management and pfsync for now,
where 670Mbit/s is plenty for those tasks.
I've attached a dmesg and pcidump for those that are interested.
Thanks,
Jason
