• Pack discovery reads metadata on a worker pool instead of one pack at a time on the main thread.
• pack.mcmeta is read once per pack instead of once per metadata section. Vanilla reopens and reparses it four times.
• Zip packs are indexed once and looked up by prefix, instead of walking the whole archive on every findResources and getNamespaces call. Vanilla rebuilds and UTF-8 decodes every entry name on each pass.
• Server pack metadata is read in parallel. It runs before the loading screen exists, so a large pack froze the window there with no progress bar.
• Font glyph coverage is resolved across cores. Above a few hundred fonts it switches to a claim-based pass that cuts the work from (code points x fonts) to roughly (code points).
• The glyph warm-up loop is skipped when no font in the set caches on access, which is every vanilla font except TrueType. On a bitmap-font pack it was pure waste.
