A low-latency scheduling patch for 2.4.15-pre4/pre5 is at http://www.zip.com.au/~akpm/linux/schedlat.html#downloads This is a general retune, retest and review. A couple of bugs which have crept into the patch were fixed. ext3 support is added. Certain code paths which were introduced into the kernel in the 2.4.9-2.4.11 timeframe have been addressed. On a single 850MHz PIII with 768 megs of RAM and 1G of swap the worst case interrupt-to-activation scheduling latency is around 400 microseconds. Latencies on SMP are up to 1000 microseconds. These measurements are across extreme workloads - peak latency across an SMP kernel build is 260 microseconds. - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
