We have rolled out the 512 wae's to the edge offices and a couple of the 7236 wae's to the core and running the 4.0.19 code level. We have centralized all the data on the core and allowing only cifs traffic for optimization/acceleration. What we have noticed during the testing was a high latency on especially openning big files, like anything over 30 MB. Upon further investigation, we came out with the oplock as the culprit. Does anybody know any way of either remetiating this issue or some kind of a work around? We have tested the MS apps and some custom apps..
