Yes. But it will nit fix non-cached access to the disk (raw) devices. And
this is the main reason why ntfs-3g and exfat are much slower then working

But _that_ can be fixed with the appropriate application of a sensible
caching layer.
With every application? :) Are you know anyone who wants to do this? At
least for 3 fuse filesystems.
Also, caching in user-land is much slower and more dangerous.
There is a libublio utility which is done to provide userland caching
(it implements pwrite/pread replacement) and it is in use by this 2 ports.
So if there are alignment issues, let's fix those up first so
filesystems act sensibly with the block device layer. Then yes, adding
a caching layer that works. I didn't get very good performance with
g_cache when i last tried it.
Because its very primitive. Once again - try to compare performance of
the exfat or ntfs-3g on Linux and FreeBSD. Raw device speed (i used USB)
is pretty the same, but resulting speed is very different, as well as
I/O characteristic.
