[Nagiosplug-devel] RFC: Nagios 3 and Embedded Perl Plugins

[Thomas Guyot-Sionnest]

If I understand it correctly, it could also make Nagios crash and leak
memory much more easily.

C plugins are very fast already and can behave pretty badly without
affecting the main process. What performance gain could we expect going
from C to dynamically loaded plugins?
