Slow Part Transaction's... Take 30-50 Sec to Run

Running Part Transactions are VERY slow in E9, the following transactions we have observed this slowness:
Receipt Entry
Inventory Transfer
Quantity Adjustments
Processing a Material Queue (MES/Handheld)
Issue Inventory
I'm 30 seconds is the average time, but remote offices on T1 WAN links take up to 50 seconds each.
We did not have this level of poor performance in Vantage 8.
