Update on our system:
Seeing the same issues with a little less lag since the EOM adjustments; I looked at the OS itself. Some network tweaks seem to have sped up the file access time through loopback, as well as the overall network performance.
Disabling Network Task Scheduler and "My Network Places" shares, as well as some packet tweaks.

also disabling "last access" regestry entry on the filesystem seems to have sped up the file access time since it's one less thing it logs before opening a file. I cannot verify if the software uses this entry for anything, song-rotation comes to mind if you use the system that way.
I've also started using a batch script I made a long time ago that "refreshes" those pesky Mapped Network Drives
Sometimes when rebooting a computer it will show a "Disconnected Network Drive" in My Computer - this is because the user hasn't opened that drive since the reboot and most software will not send authentication to access the drive (assuming it's already auth).
My script just opens each mapped drive and request a directory listing, then closes.
remap.bat
----------------------------
echo off
L:\
dir
O:\
dir
[any other mapped drive letter]
dir
exit
----------------------------
save this in a folder on each computer (local drive) and setup a scheduled task to run it every
n minutes. Also put it in the startup folder for reboots.
If you set the Scheduled Task to run as a different user you will never see the DOS window either.
This little script will get your machines reconnected if, for any reason, your network drops.
