I've been able to revisit this one. Firstly, the 'duff' card that allowed me to crash the system wasn't a realtek (yes, I know where to file those), but a D-Link DFE530TX - ie not something I'd have associated with poor quality. Anyway, I've now replaced it with an Intel card - so internal is e1000 driver, external is e100 driver. My box (1GHz Pentium, 256M RAM) can route (and count) a full 6Mbps, but as soon as I turn on traffic control, throughput drops to about 4Mbps. I'm guessing that the packet handling for traffic control is substantially more complicated than for routing and accounting. Anyone got any more ideas ? Since this isn't directly Shorewall related, anyone got any suggestions for more appropriate places to look for help ? ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
