As UNIX is so file I/O intensive, what kind of performance can MachTen have if Apples file system is so slow?
Naturally, having a fast UNIX file system on the bare hardware would give better performance. But having lots of memory and making sure that you have a fast hard disk and a fast software disk driver go a long way to ensuring good performance. Tenon plans to extend MachTen with a native UNIX file system in the future.
