You don't even have to defrag windows.

However there /is/ a performance boost from defraging a file system.

Only if you have a very poorly designed filesystem.
*Very* poorly designed.

You don't understand file system.

I understand filesystem and that he was talking about disk based
filesystems.
Disks are faster if you can stream the file without having to do seeks..
without defragging and compaction you will end up with files that require
seeks and it will slow the system down.

Yep, you don't understand filesystems. (Or harddisks
either!)

The only systems where this isn't true are specialised ones like some
databases use and even then the database will have some sort of optimisation
built in.

There is no need for defragmentation on any of the
modern filesystems that have been designed for unix
based systems.

Windows filesystems are the only ones that require it.
