今日性能亮点：Claude Code CLI 现在 p99 的 CPU 占用减少了 2 倍。 Bun 的垃圾回收器原本按固定定时器运行，会在回合中途触发，恰好在 Claude Code 最繁忙时抢走 CPU。现在它会等到进程空闲时才运行。https://t.co/icGc35LDQs

Perf win of the day: Claude Code CLI now uses 2x less CPU at p99.
Bun's garbage collector was running on a fixed timer, so it would kick in mid-turn and steal CPU right when Claude Code was busiest. Now it waits until the process is idle. https://t.co/icGc35LDQs
