jmtpfs lists directories much slower than go-mtpfs and simple-mtpfs, sometimes over 50 seconds in directories with only one child. The same directories tend to be affected every time for me.

This is especially unfortunate, because jmtpfs reads files the fastest of all of the clients I’ve tried so far.

$ cd /mnt/phone
$ time ls

ls --color=tty  0.00s user 0.00s system 1% cpu 0.097 total

$ cd Internal\ shared\ storage
$ time ls

$ cd DCIM
