Ah, virtualization again. Yes, that's no good for performance ;-)
There's a "defragment disk" button in VMware which simply copies the
flat file on the filesystem in order to remove fragmentation. I guess
running xfs_fsr would help more in that case. Did you try with that?

It's a pity that there's no option to define how large each chunk should
be. Using 1-50MB of real disk space for each new chunk could help a lot
to keep the file less fragmented. It get's really funny when you run
"defrag" within the VM on a sparse vdisk.
