Explanation

In the above the dataflow network, the message reports that performance is harmed. This is caused by process P1 writing to an external output and introducing a synchronization point that negatively affects performance. Route that output through process P2 so that it becomes part of the dataflow.

Note that this warning is only relevant when the block level protocol is ap_ctrl_hs or ap_ctrl_chain.
