Using Dell 1550's w/ 2 cpu's and G-NIC-II's running back to back we got 850Mbps, after the bridge was inserted w/ filtering, performance dropped to 650Mbps. CPU usage on the bridge box had hit ~65% on both CPU's. No tuning was done on the boxes for those tests. -Mike _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
