The Merge Join transformation provides an output that is generated by joining two sorted datasets using a FULL, LEFT, or INNER join. So if you are using multiple merge join then you have to use sort transformation and of course it will affect performance.

Lookup can sometimes be used in a similar manner to Merge join for data matching.
