Thank you Eric. This is the second time someone has mentioned this to me. I imagine it's a significant change. When build 89 is released, I'll be sure to upgrade. As for the speed issue, the bottom line is that I discovered a faulty NIC on the WinXP box. Through gathering performance results, I found that the WinXP box performance on read was less than a WinXP vm! After swapping out cables and using different ports on the switch I found no change. However, after swapping NICs on the mobo I gained a huge increase in write speed. I'm not sure why only CIFS had issue, probably because it's one of the chattiest protocols ever, but that's just a random jab and has no basis in fact. :) On to the results: Stats are taken with System Monitor (v2.18.2) on Solaris. I've verified the stats are similar, if not identical, on the WinXP virtual machine and on the linux box through conky. All boxes are 100fdx. The PS3 is 1000fdx. They are all plugged into the same swtich (Netgear G5605 v2, 5 port 10/100/1000). File transfers are with a 4GB file for SMB and FTP. The HTTP transfer is with a 1.6GB file. WinXP(1) = virtual machine on the linux box WinXP(2) = physical machine WinXP(1): FTP Not tested HTTP Read: 500KiB/s - 2.7MiB/s SMB Read: 1.1MiB/s - 3.4MiB/s Write: 2.2MiB/s - 3.4MiB/s WinXP(2): FTP Read: 4.2MiB/s - 9.9MiB/s Write: 1.9MiB/s - 6.0MiB/s HTTP Read: 2.4MiB/s - 6.5MiB/s SMB Read: 7.6MiB/s - 8.3MiB/s Write: 7.9MiB/s - 8.9MiB/s Linux (100fdx) FTP Read: 1.8MiB/s - 3.7MiB/s Write: 3.6MiB/s - 3.7MiB/s HTTP Read: 2.5MiB/s - 4MiB/s PS3 (1000fdx): DLNA Read: 9.4MiB/s The end result is that I have 63.75 Mbps - 74.66 Mbps read/write via CIFS. Not too bad considering it's really just a 100Mbit network link. Sorry to spam. I thought for sure that the high read/write speeds for FTP and HTTP showed that the issue was with CIFS. I'm still kind of baffled as to why CIFS was so terrible for the write speed only when, in the end, the issue was the NIC. Thanks to those that helped. rick This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
