"dont fragment flag" itself can't be a reason for performance issues as it allows fragmentation, but don't requires it.

You have to check if there is an actual fragmentation happening on the network (look for Fragmented IP Protocol caption.)

This is to be checked at the receiver side and may happen of you have some kind of tunneling on the path.
