DS7.1 / DCOM : Is it possible to read multiple channels at the same time?

Is it possible to read more than one channel at the same time using DCOM on DS7.1?

Right now I'm building a list of channels and I iterate over this list. For each channel I read its DBValues[posToRead].

When used on the same machine it works OK but on a remote machine it's very slow.

Is there a better way?

unfortunately there is no way to read multiple channels at once. You will have to stick with itterating over every channel like you've been doing so far.

I have the same or similar problem - actually the timing is quite variable and sometimes slow (several hundred msec) to query a handful of channels, even on the same machine. I just want to get the latest sample from each channel. Is there a faster way to do this? Would another interface besides DCOM work better?
