Description
Is there some way of building or enabling multi-core support for image_transport compression?
I don't know about PNG but the JPEG compression algorithm pretty naturally lends itself to parallelisation. I was wondering if this was implemented and possible to switch on?
If not, would a patch optionally enabling multicore compression be welcome?

Research direction
Start by locating the image_transport compression implementation and checking how JPEG and PNG compression are currently built or enabled. Determine whether either backend exposes multicore support and what an optional configuration would need to cover. Done would mean an agreed implementation approach, rather than only confirming that parallel compression is possible.
