The problem I/we have with NSCA is not that of performance. We
provide Nagios services to a large-ish user base (>100 users).
As a result, a single user interface for those users is a must.
With NSCA, said UI is degraded: you can't reschedule a check or
disable checking entirely from the central machine, since there
is no backchannel to the checking nodes. Also, the UI is very
misleading with purely passive checks on the central machines: it
looks like all checks are disabled *entirely* in the web
interface (this could be fixed by hacking the CGIs).

DNX' approach with "dishing out" checks to waiting nodes solves
these problems. Unfortunately, it quickly rendered the central
machine absolutely useless with huge load and memory consumption
last time I checked.

Regards,
Tobias
