_Performance numbers_:

Windows - Same host as Linux, a preview version of Windows 11.
	  This number is from a patch later in the series.

Adding 500 files to the repo with 'git add' Times reported in seconds.

core.fsyncObjectFiles | Linux | Mac   | Windows
----------------------|-------|-------|--------
                 false | 0.06  |  0.35 | 0.61
                 true  | 1.88  | 11.18 | 2.47
                 batch | 0.15  |  0.41 | 1.53

Interesting here the performance.

You said that core.fsyncObjectFiles=batch performed 2.5x slower than core.fsyncObjectFile=false on Linux and Windows, why?
