Alexey and I have been using 16 threads.
You don't tell us how much memory your lab machine has. The above command only makes sense if it is less than 400 megabytes. Otherwise many or all of the reads are satisfied from pagecache.
I've been testing with mem=256M, --file-total-size=2G. - 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/
