问题 I ported a multi-threaded Linux application to Windows and am testing it on a server running Windows 10 Pro. The performance of the Windows version is abysmal compared to the performance of the Linux version running on the same dual-boot hardware. I simplified the code to a small multi-threaded example that exhibits the same symptoms. I am hoping that the SO community can provide some insight as to why there are such performance differences between Windows and Linux for this application, and

问题 I'm trying to execute a command with git-bash using cmd. I need to pass the command for it to execute. The problem is I need to pass the path of the batch file into the command and it has spaces.
