I can be wrong. As I see ZFS cretate seperate thread for earch txg writing. Also for writing to L2ARC. As result -- up to several thousands threads created and destoyed per second. And hundreds thousands page allocations, zeroing, maping unmaping and freeing per seconds. Very high overhead.
In systat -vmstat I see totfr up to 600000, prcfr up to 200000. Estimated overhead -- 30% of system time. Can anybody implement thread and page pool for txg? _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
