If you find yourself backtesting the same symbol & time period over and over, a slight speed increase can be obtained by saving an FXT file and reusing it instead of using compressed data from the repository every time.
On a modern PC, having a pre-saved FXT would save about 1 minute for the whole Dukascopy EURUSD data range (2003-2016).
This would be an option that would be controllable from the Tick data settings dialog; the default value would be in the Tick Data Suite support assistant, in the Settings section.
Among other factors, planned features will be scheduled for implementation based on user preference. Press Yes below next to "Did you find it helpful?" if you'd like this feature to be prioritized for implementation. Feel free to press No if it's not a priority for you.
