Hi,

What evidence do you have that MBR volumes have better performance than
GPT volumes on Windows?

I've run into offset problems with DOS partitions on Linux, where the
offset forces every write at the filesystem level to be written to two
stripes rather than one. You can fix this with the "x b" command in
fdisk, or use LVM which doesn't have an offset.

I don't know if this is related to MBR/GPT on Windows though.
