我看也没慢多少，也就1-2s的样子，xrepo env 每次都会创建一个干净的 empty project 去处理，默认 windows 平台的 msvc 是避免不了的。

只是觉得开了 verbose 更快了有点诡异

这边没明显区别，-vD 下还慢了点

不太懂，可能和 bat 有关，直接 xmake l private.xrepo 速度就差不多了。

Just think it's a bit weird if you drive verbose faster

bat 里面额外执行了一些东西

xmake/scripts/xrepo.bat

Lines 24 to 28 in a8ac818

	"%XMAKE_PROGRAM_FILE%" lua private.xrepo.action.env.info config
	if !errorlevel! neq 0 (
	exit /B !errorlevel!
	)
	@"%XMAKE_PROGRAM_FILE%" lua --quiet private.xrepo.action.env.info prompt 1>nul

xmake/scripts/xrepo.bat

Lines 55 to 57 in a8ac818

	for /f %%i in ('@"%XMAKE_PROGRAM_FILE%" lua --quiet private.xrepo.action.env.info prompt') do @(
	@set "PROMPT=%%i %PROMPT%"
	)
