Why is my XP to Vista network file transfer speed so incredibly bad? (picture inside)

[jmk396]

I have a very simple network and recently upgraded to a GbE switch so my two primary machines are now connected via GbE. One machine runs Windows XP and one is Vista Premium.

I'm using ATTO to test the transfer speed between these two machines (from XP to Vista) and the speed seems incredibly slow.

Drive Z: in the picture is mapped to the Vista machine via CIFS (eg. \\HTPC\Storage).

The Vista machine has an IDE hard drive (ATA 133), but these speeds still seem rediculous.

As a comparison, here is the same test done locally on the Vista machine: (which still seems really, really bad)

This is a known issue with Vista. If you want speed, go with XP. If you want security, go with Vista. SP1 will dramatically increase network speed.
