udpsrc performance

[parag.salasakar]

Hi

Thanks for the suggestion.

I tried it with udpsrc properties blocksize=50000 buffer-size=50000, but
observed same issue (udpsrc taking 35-40%)

Does your suggestion mean that I have to modify source code for udpsrc
plugin which allocates buffer-pool and re-use them?

Regards,

Parag
