I've noticed some network operations on the LAN going slower than usual over the past few weeks but hadn't had the chance to really pay much attention to it.

Today I was making some edits to music on a Windows from my Mac and it was painfully obvious things weren't going as fast as they used to.

So I did a quick test... Transferring a 150MB folder of MP3 files averaging 6MB or so in size I was getting about 1-1.5MB/s average on 802.11n. On 802.11g I get over 2MB.

I tested both to the Windows share as well as to my Time Machine share with the same results. The Windows machine says it's only using less than 1% CPU and less than half a percent of network bandwidth when all this is going on.

I'm pretty sure I used to get about 7MB+/s using 802.11n

Anyone else see any similar strange behavior after updating to Mac OS 10.5.7? It's the most major change I can think of that I've done to the system in the past month.
