Hi,
What about the disk access is unaligned? Do you mean not sector aligned? or?
Hi. Sector aligned.
This is a common problem people face doing disk IO analysis.
The whole point about not allowing unaligned access is to make the
disk IO path cleaner. It does mean that the filesystem code (and GEOM
modules involved) need to be smarter.
If the filesystem is doing ridiculously unaligned access then it
likely should be fixed.
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 on Linux.
