My tests show that the standard 2.6.14 kernel will cause xruns of up to 10ms. You can get this down to 1ms or so by doing: sysctl -w net.core.netdev_max_backlog=5 (prevents network tx/rx softirqs from causing xruns) echo 32 > /sys/block/hd*/queue/max_sectors_kb (prevent long running disk IRQ handlers from causing xruns) These results are completely reproducible on my system. They will probably lower disk and network throughput a little, but any low latency solution will. Lee
