cygwin 上的 bspwm - 重绘缓慢问题

  • 772

我已经设法在 cygwin 2.10.0(0.325/5/3) (Windows 7) 下编译 bspwm 平铺窗口管理器，与 Openbox、LXDE 或 fwvm 相比，性能相当糟糕。你能给我一些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，我需要多个终端窗口。将它装箱在 bspwm 的一个窗口中会非常方便，并且允许我根据需要设置我的终端工作区。

症状：

  • 通过 Shift + PgUp 或 PgDown 在终端（urxvt）中滚动时重绘速度较慢
  • Terminator 快一点，但打字很慢。
  • 节点切换、在桌面之间跳转等命令的执行延迟约为 300 毫秒（只是一个猜测）。这是相当小的，但它让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，即使在运行大型 vim 文件等时，urxvt 也能快速启动。

首先这是我的 XWin 启动日志：

    缓慢是由 rxvt 终端仿真器引起的，尤其是当它在 bspwmrc 文件中自动启动时。我现在使用 xterm 或 terminator 并且 bspwm 很快。

    我已尝试使用 strace 查找原因，但没有得到任何显示可能存在问题的信息。
