Help with analysing JIT perf report

I've checked it without lcnt and situation is the same.
I have NIF ERL_NIF_DIRTY_JOB_IO_BOUND that uses enif_select to read
data with function read from DVB card.
I've seen that this pause instruction is somewhere nearby driver_entry@REDACTED
I've checked: one process that reads data from DVB card gets about 350
ready_input messages per second.
Maybe I don't need to use ERL_NIF_DIRTY_JOB_IO_BOUND flag if I know
that socket is ready for reading and non-blocked?
