On anotherĀ  note I use 'gr_block' to build this custom block

I have a modified dbpsk.py in which I use a custom block after the self.diffenc (differential encoder block). This custom C++ block outputs 1000 output_items of size 'gr_sizeof_char' for each input_item of size 'gr_sizeof_char'. I then use benchmark_tx.py to test the functioning of the modified dbpsk.py and upon doing so the flowgraph slows down incredibly. What can I do to speed up the process?

DiffEnc --> Custom Block --> Chunks2Symbols
( n ouputs) --> (n * 1000 outputs) --> (n *1000 outputs)
