Replacing it with a different nic might do the trick.
I'll try that anyway.
John already suggeted a Gb-nic, but it's not the speed that might do the trick for you, modern nics (capable of realy doing Gb) often have longer hareware fifo's onboard, and generate less IRQ's for the same amount of data, compared with 3com's. Might consider a single Intel board with quad E1000 if irq's or the bus is a problem.
I've also got some fairly ancient Sun HMEs with 4x100Mbit, but they're 64bit PCI cards. I still might experiment.
Does anyone have any real suggestion as to why a 100Mbit ethernet card cannot handle 50Mbit? It doesn't matter much, but it doesn't seem to make much sense?
Per, Don't know if possible, but can you exclude any other influences? Normally (indeed...) it is not difficult to compleely saturate a 100Mb card, a bit harder to it for a 1Gb card, and it takes some effort to saturate a 10Gb card. Besides the droppings (shouldn't happen), how did you measure the throughput? As to the 'why question", i've witnesed mobo's, mem and nic's gone bad long after an ESD-event. And i'm not talking about lightning, but simply unsafe removing/installing components in a pc. Dutch telco KPN did some research on their own people and corelated it with failure events. After they implemented their strict "clean" policy the number of unexplained hw-failures dropped significantly. In their instruction-movie, they shown pictures from microscopic reseach on chips and pcb's. Something i'll never forget. hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
