Latency of E4440A spectrum analyzer

What is the expected latency of network communications to the E4440A or other spectrum analyzers. In my case, after doing a sweep, it takes about 3 seconds to fetch the X and Y points (1001 points). Reducing the number of points doesn't seem to effect the latency. Then later I fetch just two data points, and that also takes about 3 seconds. All those seconds add up. The sweep itself is only about 0.3 seconds.

I'm using IVI-com. I seem to remember an app note on increasing the data rate. Does anyone know what that app note is?

Thanks.
