> The patch is against 2.4.19-pre2. The patch significantly lowers BKL contention (50%) on a 2-way PII-300 running dbench 4. Dbench throughput is not significantly affected, but that is probably a function of my puny little machine more than the effectiveness of the patch. I'll have some results on a much more beefy 8-way PIII tomorrow. Earlier versions of the patch reduced BKL contention during dbench by 60% on the 8-way. CPU utilization spinning on the BKL has been as high as 40%.
I certainly am not interested in it. 2.4 locking changes for very big boxes
strike me as a little dangerous.
