xQueue between cores takes long time

[someburner]

FWIW I have timed queue tx -> rx between cores to be 20us on average in my application (that does not do any heavy processing). Task notify is barely faster. In my case I'm sending from high priority task on Core 1 -> medium priority on Core 0. All wifi / network / sdk tasks are on core 0. Max latency is like 500us with logging off when receiving/processing an mqtt message.
