我说为什么在Ace的窗口过程里执行eval这么慢呢

Shy07

When benchmarking basic requests with a minimalistic schema (only one int column), even though YARV serviced requests 15% faster, it took much longer to load the environment (50% slower). This comes as no surprise since plain old (evil) eval is slower in YARV(...)In fact, the mere fact of requiring active_record (and indirectly ActiveSupport) causes a sharp decrease in performance.

eigenclass.org的测试结果，在YARV上执行的RoR比在1.8.6上执行要快15%，但是启动时加载环境慢了50%（记得以前在哪里看过，说Ruby每次eval都要修改环境）
So，在窗口过程里用eval获取窗口消息这种方法在Ace里会变得奇慢（限制一下CPU掉帧会变得非常明显）

消息太多（

精简过好多次了，最后只是单纯赋值操作还是能感觉到卡：（
