tree command is painfully slow

Hello ish-app Team,

Thank you for this awesome way of playing (messing ;-)) around with Linux on iOS Devices.
I wanted to know what causes I/O in general to be so slow when it comes to mounted filesystems like, i.e. `mount -t iOS . /mnt/abc`: one example is the `tree`

Is this because of emulation?

Another example is `exiftool` takes several seconds to load. Even `java` seems to boot a bit quicker…

Any insights?
Thanks,
Jo

Reproduce the slowdown with tree and exiftool on a mounted filesystem, then compare their behavior with a local filesystem and investigate whether emulation is involved. Done means the cause of the I/O slowdown and a concrete scope for improvement are established.
