I don't think that 200 updates per second is actually going to happen with
anything other than a random number generator. One of the RTDs that I've
worked with have been for trade execution average prices, so they are hooked
up to a TIB (www.tibco.com) backbone to update average prices for orders.
This will tick over with many three events per subject per second at most, so
it's really not hitting the limit.

What is going on in your RTD server? What are you calculating? What's the
client side hardware? Where does the data come from? These are some of the
questions that you need to look at to see what the problem is.

Hello group,

I really need help here - and the faster the better because we got
stuck!!!

RTD FAQ on MS site
(http://msdn.microsoft.com/library/de...c_xlrtdfaq.asp
) claims that maximum frequency for updating one topic is 200 updates
per second.
In our attempts to calculate the frequency with which Excel is able to
refresh data we couldn't get more than 63-65 updates per second.
Did anyone try it and got 200 updates per second? If yes what is the
structure of your RTD server.

TIA,
marsou
