We are using RS232. Using the XFlash unit as configured through spec does not show the same delay as the IOC. Disabling the Temperature monitoring PV (:ReadTemperature) which is on a 1s scan-rate, seems to alleviate the problem a bit.

Over what physical link are you communicating with the XFlash? If it's RS-232, it could just take that long to transmit the data over the slow link. Lewis
