Too slow #5

Open edge2992 opened 1 year ago

edge2992 commented 1 year ago

On some systems, the measure and metrics commands are awfully slow. Adding another call makes things even slower.

Luckily, this metrics call duplicates a call in flush. If you’re careful you can pass the results of that call to DrawText as an argument.

You can profile Python programs by replacing your python3 command with python3 -m cProfile. Look for the lines corresponding to the measure and metrics calls to see how much time is spent measuring text.
