Summary
SUMMARY: Performance "Speedup quicksave (mapbuffer::save) by limiting
ui_manager::redraw()
rate"Purpose of change
While profiling auto-/quicksave I noticed that 50% of time is spent in
ui_manager::redraw()
.Describe the solution
Change the
ui_manager::redraw();
invocation to be time-based (every ½ second, similar to waiting/crafting) instead of counter-based.Describe alternatives you've considered
Limit the current counter-based UI refresh rate. Seems like a worse alternative: counter could be tuned only to a single specific scenario (number of submaps that actually need to be saved, submap saving time), while time-based approach always work as designed.
Testing
Manually playtested using quicksave.
