Point performance is based on the number of points being processed. If your project is set up with 2 points, for example, v1 and v125, it will get every point in between and process each one, thus slowing performance.
You can do the following to optimize the performance of points:
Use staggered scan rates.
Avoid gaps in allocated data addresses or use small gaps. This will reduce the transfer of "meaningless" values.
