Update on this. I setup the storage system for more stable runs and repeated the above test. It runs a bit faster as well, completes the workload at 2.5GB/sec average. Cache stats (millions) Kernel References Misses ---------------------------------------------- baseline 3384 2318 baseline 3417 2313 baseline 3382 2323 baseline avg 3394 2318 patched 3518 2258 patched 3428 2201 patched 3536 2274 patched avg 3494 2244 So for those runs, ~3% more references and ~3 less misses. Even with the variability here, that looks like a win in my book. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
