Defragmenting NTFS/FAT32 drives, differences?

A question on defragmentation.
It appears to me that defragmenting a NTFS drive is a lot quicker than defragmenting a FAT32 drive.
Is it obvious that it has to be so?
I use Windows XP with Diskeeper 8.0

Thank you very much!

Hello Michael;
I think the speed is caused by defragmentation percent. I can't think of an another explanation to this.

Also presentage fragment and different FS structure as well...

"NTFS Performance

Disk subsystem performance is a critically important factor in overall system performance, and NTFS is generally believed to be slower than FAT. However, with a correctly created NTFS volume, NTFS performance optimizations, and <improved disk defragmentation>, NTFS performance (including the extra "journaling") is equivalent to FAT on small disks and is faster than FAT on large disks."

To echo the prior 2 posts...NTFS is "resistant" to fragmentation...which means that when you do a defrag, it is likely that your level of fragmentation will be lower for NTFS than FAT32. It should also be noted that NTFS can be subject to more complex fragmentation than FAT32, so a regular defrag can be beneficial.

Also, if you are comparing the old Win9x defrag tool to the XP defrag tool (or to Diskeeper), there is a huge difference in the performance of the two tools.  The defrag tool in win2K and up is in fact licensed from Executive Software, the same vendor who makes Diskeeper.

Don't forget the most obvious one, size.

The reason an ntfs drive is faster to defrag than  fat32 is becaue it gets less fragmented because the fie chunks are broken into larger blocks making it so that less rearranging ha sto be done in orde to defragment.
