Very slow getattr in some directories #34

Open delan opened 5 months ago

delan commented 5 months ago

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.
