The two worst hot paths were:
- clicking a row triggered a full table rebuild with sort+innerHTML
(queue AND recent panel), and the opposite panel got cleared with
another full rebuild
- every upload progress tick (4/sec) scanned queueJobs twice and
filtered sessionFilesData twice just to update the status bar
Fixes:
- applyQueueSelectionClasses / applyRecentSelectionClasses toggle the
.selected class on existing rows instead of rebuilding the tbody.
Click selection is now O(rendered rows) instead of O(total × sort).
- maybeAddSessionFile schedules renderRecentUploadsPanel via rAF so
a batch of 1000 successful uploads coalesces into one render.
- sortRecentFiles memoizes its result per (sortKey, direction, len)
— unchanged sort state + unchanged length returns the cached array
instead of re-sorting thousands of entries.
- _computeQueueStats now also returns inProgressBytes, dropping the
second queueJobs scan in updateStatusBar.
- session done/error counts are maintained incrementally, replacing
two sessionFilesData.filter().length calls every status-bar tick.
- handleRowClick uses the _jobIndexById map instead of Array.find.
