Hi,
I've got OpenBSD 4.0 (release) on a laptop setup up as a router between 2
subnets, and providing internet access through a 3rd nic to a DSL modem.
The problem is the bandwidth between the two subnets. I'm only getting a
maximum of about 500 KB/s between two 100mbit cards.
Top shows ~70% interrupt (~29% idle) while these transfers are going on.
I don't know what the bottleneck is in the system. Are the Linksys PCMCIA nics
crappy? Did I screw something else up?
As a test I turned off pf and did ftp transfers from the OpenBSD machine
to/from each subnet, and the bandwidth was still limited to ~500 KB/s, so I
don't think it's anything in my pf setup.
Thanks
