With using java 17 on Windows more then half of the time cloning is spend in java.io.File.getCanonicalPath () called from constructor org.eclipse.jgit.internal.storage.file.ObjectDirectory.AlternateHandle.Id.Id(File).

That is because getCanonicalPath does not cache the result anymore.

Please avoid using getCanonicalPath(): I am sure git does not want to let the OS compute the actual capitalization of all directories in the files path nor follow links.

May be the cheap File:getAbsolutePath() is enough?

Or if you really need to rely on the OS here then java.nio.file.Files.getFileAttributeView(Path, Class<V>, LinkOption...) + java.nio.file.attribute.BasicFileAttributes.fileKey() could be used instead - since the name is used for comparison only anyway.
