Re: [zfs-discuss] [zfs-code] Peak every 4-5 second

[Tharindu Rukshan Bamunuarachchi]

We do not use raidz*. Virtually, no raid or stripe through OS. We have 4 disk RAID1 volumes.  RAID1 was created from CAM on 2540. 2540 does not have RAID 1+0 or 0+1. cheers tharindu Brandon High wrote: On Tue, Jul 22, 2008 at 10:35 PM, Tharindu Rukshan Bamunuarachchi <[EMAIL PROTECTED]> wrote: Dear Mark/All, Our trading system is writing to local and/or array volume at 10k messages per second. Each message is about 700bytes in size. Before ZFS, we used UFS. Even with UFS, there was evey 5 second peak due to fsflush invocation. However each peak is about ~5ms. Our application can not recover from such higher latency. Is the pool using raidz, raidz2, or mirroring? How many drives are you using? -B
