Depends on filesize and stripe size, really.

When a transfer is not the full stripe width the transfer is slower than
optimal.

Depends on filesize and stripe size.
You choose your stripe size depending on filesize and stripe width.

If you change the stripe width without changing the stripe size then small
files may find themselfs sitting in a less that full stripe(width) and not
benefit from the same full stripewidth transfer rate that bigger files get.

Sure, when you don't adjust your stripe size accordingly.
