Hello, Indeed the times you get do not sum up. On my rather low-end computer (dual core, 3 year old athlon) using eSignal as a data source and 8 charts displayed simultaneously and all visible, the total display time is only 0.094 sec and it is perfectly responsive.
I guess that this has to do something with the database settings you are using. Please send screenshots of your File->Database settings to support.
