Description

Prerendering SVG icons and making all SVG loading async together lowered startup time on my machine by 33%. I added a simple two-line way of measuring startup time (see startup-measurement.diff) and produced the following output on my machine.

Before: (revision 19547 with only startup-measurement.diff applied)

2026-03-17 21:48:47.795 INFO: Startup complete in 13919 ms
2026-03-17 21:49:17.480 INFO: Startup complete in 13917 ms
2026-03-17 21:51:04.253 INFO: Startup complete in 13475 ms

After: (revision 19547 with both startup-measurement.diff and startup-performance.diff applied)

2026-03-17 23:26:31.053 INFO: Startup complete in 8902 ms
2026-03-17 23:26:48.479 INFO: Startup complete in 8870 ms
2026-03-17 23:27:04.865 INFO: Startup complete in 7950 ms

I tested on macOS 15.7.3, all tests ran, and pmd emitted no issues that affected either of the files my diffs touch.
