Custom library causes performance issues on Studio and Robot.
There are 2 parts in the slowness.
1. library validation time (which took ~3 minutes)
2. time takes before execution begins (which took around 1:30 - 2 minutes)
For 1, the product team concluded there is no room for improvement in the implementation that performs the validation.
If the library is large and complicated, it would need some time to validate.
A best practice here is to keep each library small, and have more of them if needed.
For 2, the product team has implemented an improvement and the time required would be reduced by 50%.
The fix will be in the next version 20.10.
