It seems that zfs with compression enabled on > /usr/src with 8KB block size and 16 threads performs 386.3MB/s which > is about 6 times better than debian5? I am thinking about this image > http://tech-blog.wooh.hu/~wooh/debian_vs_freebsd_io_16_seqwr.png Yes - on one run it even hit 500MB/s. I suspect, however, that the benchmark isn't accurate because it won't be writing typical data. Instead it's probably using a buffer that compresses very well. -- Bruce Cran _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
