cygwin 上的 bspwm - 重繪緩慢問題

我已經設法在 cygwin 2.10.0(0.325/5/3) (Windows 7) 下編譯 bspwm 平鋪視窗管理器，與 Openbox、LXDE 或 fwvm 相比，性能相當差。你能建議我一些如何解決這個問題的想法嗎？

有時我需要在 windows 下測試一些 linux bash 腳本和命令，我需要多個終端視窗。將它裝箱在 bspwm 的一個視窗中會非常方便，並且允許我根據需要設置我的終端工作區。

症狀：

• 通過 Shift + PgUp 或 PgDown 在終端（urxvt）中滾動時重繪速度緩慢
• 終結者有點快，但打字很慢。
• 節點切換、桌面間跳轉等命令的執行延遲約為 300 毫秒（只是猜測）。這是相當小的，但它使工作流程感覺不愉快。

一些應用程序即使在 Openbox 或 Fvwm 下也需要一些時間才能啟動，但 gui 響應速度很快，即使在執行大型 vim 文件等時 urxvt 也很快。

首先，這是我的 XWin 啟動日誌：

緩慢是由 rxvt 終端仿真器引起的，尤其是當它在 bspwmrc 文件中自動啟動時。我現在正在使用 xterm 或 terminator 並且 bspwm 很快。

我已經嘗試 strace 找出原因，但我沒有得到任何顯示可能存在問題的資訊。
