Hi Here is more specs.
MB: K8N4-E SE - AMD Socket 754 CPU - NVIDIA® nForce™ 4 4X - PCI Express Architecture - Gigabit LAN - 4 SATA RAID Ports - 10 USB2.0 Ports http://www.asus.com/product.aspx?P_ID=TBx7PakpparxrK89&templete=2 Now situation is this : with ftp : i can upload to datapool with speed ~45MB/s download from datapool only with speed ~ 750 KB/s So it is now read performance that is a problem. Could it really be that nvidia network and sata drivers now share same IRQ and that's why performance is slow. Mar 23 19:35:01 <hostname> unix: [ID 954099 kern.info] NOTICE: IRQ20 is being shared by drivers with different interrupt levels. This is just odd as this issue come when only changed pool physical disks and also changed raidz to raidz2 and also update to build 134 -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
