The two main problems are -
1) if one or more of the fragments get lost then the entire packet has to be retransmitted from the source.
2) fragmentation uses up memory buffers on the device doing the reassembly because the packet cannot be forwarded up the protocol stack on the receiving machine until all the fragments have been received and reassembled.
