The performance difference would result from TM doing write on the disk during 2PC prepare( I think it's after the prepare phase). This only happens if we run distributed transactions tough (i.e. more than one participant), otherwise the TM would optimise the call for a single resource and no disk access takes place. 
Even more, AFAIK this can be disabled not to do disk access ( keep tx log in memory). 
So I estimate the performance should be about the same.
