MultiCharts: Trading Software for Automated Trading and Backtesting

I have 5 wsp open, and the MCActiveX.exe is 564MB, tsServer.exe is 227MB.
These numbers look large. Are they normal ?

This depends on the type of workspaces you have open - please tell wat are they?
For instance, a single workspace using Bill Schamp's techniques and charting a set of 49, 343, 2401, 16807, and 117649 voulme bars for a year of data will easily consume half a gigabyte of memory.

yes, I have a few of those. But only 2 months data.
I guess it is "normal".
