Hmmm ... I took the 15 September snapshot at 
http://nagiosplug.sourceforge.net/snapshot/


[root at adnsoz05 ~]$ /opt/adnnagios/libexec/check_procs-new -V
check_procs v2019 (nagios-plugins 1.4.12)


[root at adnsoz05 ~]$ time /opt/adnnagios/libexec/check_procs-new -t 60
PROCS OK: 1445 processes

real    0m32.551s
user    0m1.641s
sys     0m26.088s

[root at adnsoz05 ~]$ time /opt/adnnagios/libexec/check_procs-1.45 -t 60
PROCS OK: 1477 processes

real    0m0.344s
user    0m0.056s
sys     0m0.309s

Still runs about 100x slower than version 1.45.
