Does market replay slow my system down?

[nucc10]

I like to record markets to practice at night. Will the more days i record slow my computer down more and more. For example if i have 10 days recorded. Will my system run slower than if i just keep the 3 most current sessions. Are these data recording stored on my hard drive? Thanks for any help with this matter.

The recorded market data is stored on your computer so it is important to shut off the recorder when you finish recording the data you need.

The data is stored here:
My Documents\NinjaTrader 6\db\data

You can delete the contents of this file if at anytime you want to be storing less data.
