Ahh... thanks for clearing me up on that, and so fast. So the problem is how to get BSD to handle packets faster. And I guess my question still is, why can't we move some of the packet-handling and routing directly into the driver where it is a few layers closer to the actual hardware. Not really off loading, but giving the packet-handling code a chunk of the CPU time (probably as much as it needs) w/o being able to be squeezed out by other processes and such. I wasn't suggesting using a 486/ISA to act as a 100mbps router, just giving you the system information to explain the 9.1 mbps thruput to localhost. Even though I wouldn't be surprised if, with properly optimized code, if one could handle it. There is a program called pc-route for DOS systems that supposedly is as fat-free as code can be [no branches in the assembly source, etc]. On a pentium with 2 100 mbps cards, I am wondering how fast it could move packets to give a theoretical packet/s maximum. Anyone have a configuration where they could try it? -Jerry.
