I am using Solaris Express Community build 67 installed on a 40GB harddrive (UFS filesystem on Solaris), dual boot with Windows XP. I have a zfsraid with 4 samsung drives. It is a [EMAIL PROTECTED] and 1GB RAM.
When I copy a 1.3G file from ZFSpool to ZFSpool the command "time cp file file2" gives this output: bash-3.00# time cp PAGEFILE.SYS pagefil3 real 0m49.719s user 0m0.004s sys 0m10.160s Which gives like 26MB/sec. When I copy that file from ZFS to UFS I get: real 0m35.091s user 0m0.004s sys 0m15.337s Which gives 37MB/sec. However, in each of the above scenarios, the "system monitor" shows that all RAM is used up and it begins to swap (the swap uses like 40MB). My system has never swapped before (Windows swaps immediately upon startup, ha!). The cpu utilization is like 50%. When I copy that file from UFS to UFS I get: real 1m36.315s user 0m0.003s sys 0m11.327s However, the CPU utilization is around 20% and RAM usage never exceeds 600MB - it doesnt use the swap. When I copy that file from ZFS to /dev/null I get this output: real 0m0.025s user 0m0.002s sys 0m0.007s which can't be correct. Is it wrong of me to use "time cp fil fil2" when measuring disk performance? I mount NTFS with packages FSWfsmisc and FSWfspart, by Moinak Ghosh (and based on Martin Rosenau's work and part of Moinak's BeleniX work) This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
