Simon, Hey Simon. I have not updated to the latest BIOS. I'm 1 or 2 revisions behind. I will check into updating, however I think that's not my issue. I do have a Cat6 cable that I'm plugging in to a 10/100/1000 switch. It's a SOHO switch which does not have a configuration interface. I do know the port works as 1000 because my last mobo was connected to the same cable and port at 1000. For whatever reason, I cannot set my nge interface to 1000 though. It runs fine, but only connects at 100 full duplex. On the same switch I also have a PS3 which connects at 1000. The typical speed from the Solaris ZFS shared data to the PS3 is 700KiB/s. That's streaming data though. The actual "copy" speed is 9.3MiB/s. Although, to be honest, I'm not sure of the protocol it uses to copy data. MediaTomb is the DLNA application that feeds my PS3. Anyway, all other devices use Cat5e and connect to the same switch (at least, all other devices that are involved in this little fiasco.) The 2MiB/s speed isn't so bad, or at least uncommon in my office. Copying from another windows box (laptop) to the winxp box, that was used in the tests quoted before, results in 2.2MiB/s - 3.4MiB/s while using MS SMB. I'm less concerned with speeds around that mark. The only speed that really concerns me is the 342KiB/s write speed. It's not a great situation when your backup solution only accepts 342KiB/s on writes. :) And for those getting annoyed, I'm aware that this is probably not a direct fault of ZFS. However, I'm not sure how exactly the code between CIFS and ZFS interfaces, so I included "zfs discuss" on my initial post. Because the read/write speeds of other protocols is faster on the same ZFS mirror, I have to assume that there is definitely an issue with CIFS or my configuration of CIFS. Still, I have not found any information at all on tweaking CIFS in Solaris. I can't even find a config file for it. :( rick This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
