Performance issues when data remains consistent, but tracker position changes

Hey, I've noticed the performance for react-timeseries-charts suffers when the tracker position changes - but the underlying dataset is constant.

As a demo - this is the simple timeseries I'm working with, it's a slightly artificial data-set but it shows the main point of being slow to respond when moving the cursor around:

It would be great if there's a way to improve the performance under this scenario
