我已经成功地在 cygwin 2.10.0(0.325/5/3) (Windows 7) 下编译了 bspwm 平铺窗口管理器，与 Openbox、LXDE 或 fwvm 相比，性能相当糟糕。您能给我建议一些如何解决这个问题的想法吗？
有时我需要在windows下测试一些linux bash脚本和命令，并且我需要多个终端窗口。将其放在 bspwm 的一个窗口中会非常方便，并且允许我根据需要设置终端工作区。
症状：
- 通过 Shift + PgUp 或 PgDown 在终端（urxvt）中滚动时重绘速度减慢
- Terminator 速度稍快一些，但打字速度相当慢。
- 节点切换、桌面之间跳转等命令的执行延迟约为 300 毫秒（只是猜测）。这是相当小的，但它使工作流程感觉不愉快。
有些应用程序即使在 Openbox 或 Fvwm 下也需要时间才能启动，但 gui 响应速度很快，urxvt 即使在运行大型 vim 文件等时也很快。
首先，这是我的 XWin 启动日志：

答案1
速度缓慢是由 rxvt 终端仿真器引起的，特别是当它在 bspwmrc 文件中自动启动时。我现在使用 xterm 或 terminator，bspwm 速度很快。
我尝试过 strace 来查找原因，但没有得到任何显示可能存在问题的信息。
