If you are sending a lot of stand-alone NSCA results, it is only natural
that you will start to get delays and hanging processes at some point
(before you reach ~1000/checks minute at current hardware).
But this should materialize itself also at the "sending" servers - is
latency there OK still?
Anyway, if this is the case, solution is to bundle up nsca checks and
only send a batch every 10-20 seconds. Should reduce load and latency
both at the sending and receiving server.
