Firefox performance spikes when too many flame cells on screen
kartikcho opened this issue · comments
The scheduler profiler seems to experience a massive performance hit when there are too many flamechart "cells" on screen at the same time.
This seems to be a browser specific issue and could be reproducible on browsers other than Firefox.
However, no similar behavior has been observed on Chrome.
Steps to reproduce:
- Load a big profile into the profiler.
- Move to an area with bigger continuous flamecharts.
- Zoom in until you have a lot of cells appearing at the same time on the screen.
- Drag and scroll around until the lag is observable.
