I really need this new nsca feature. Inter-master-slaves communication
in our test environment (about 3000 hosts and livesystem will have much
more hosts) via nsca causes the slaves' latency to grow massiv (up to
hours!). Whereas a slave with same hardware and same amount of checks
but without any ocsp/ochp does nearly nothing (latency < 1sec.!). 

I think the major bottleneck - the serial execution of ocsp/ochp still
exists in Nagios3. So Ton's comment on this
(http://altinity.blogs.com/dotorg/2006/11/caching_nsca_da.html)  is
still true.  

I expect the new PROCESS_FILE option to avoid this bottleneck. The new
nsca client has to be fast enough without any slowing down the slave
itself while reading and caching. But I really would appreciate if the
main cause of the problem - the ocsp/ohcp executions - could be
deserialized.

Let me now if I can support the development with testing, coding, ...
