A msdebug example of a long request
[Mon Oct 19 07:01:22 2009].493983 CGI Request 1 on process 10296
[Mon Oct 19 07:01:31 2009].951715 msDrawMap(): Layer 1 (roads-merged),
9.450s
[Mon Oct 19 07:01:31 2009].951777 msDrawMap(): Drawing Label Cache, 0.000s
[Mon Oct 19 07:01:31 2009].951795 msDrawMap() total time: 9.458s
[Mon Oct 19 07:01:45 2009].938752 msSaveImage() total time: 13.987s
[Mon Oct 19 07:01:45 2009].939072 mapserv request processing time (loadmap
not incl.): 23.445s
And a more normal example
