I've noticed that -current has much lower TCP performance. I haven't had time to investigate it but I presume there is some overhead somewhere that is killing it.
-Matt :Hi, :I am testing the forwarding performance of CURRENT vs. STABLE :(both more or less up to date, unmodified, with the latest performance :patches to the "dc" driver, which I am using) and I am having some :surprises. : :STABLE can forward approx 125Kpps, whereas CURRENT tops at approx 80Kpps. : :This is on the same hardware, 750MHz Athlon, fastforwarding enabled, :a 4-port 21143 card, one input driven with a stream of up to 148Kpps :(64 bytes each). : :Ability to transmit seems roughly the same (in both cases 138Kpps), :and lack of CPU does not seem to be the problem (at least for :CURRENT), so I am suspecting some difference in the initialization :of PCI parameters, such as burst size etc, but I am unclear on :where to look at. Any ideas ? : : cheers : luigi :----------------------------------+----------------------------------------- : Luigi RIZZO, [EMAIL PROTECTED] .
