you are both right on target, as i expected from this list, but i just
get scared in my debugging output when i see 500 of these
10 ms 3 ms 4 CFC[ C:\Inetpub\wwwroot\dpv\cfc\cogToDirection.cfc |
COGToDirection(286) ] from
C:\Inetpub\wwwroot\dpv\cfc\cogToDirection.cfc
and some have 10ms and some have 0ms, and i know that i normally
wouldnt see them if it were just code, but after enough of them, i
think that it will make a difference... or am i just being pre-release
paranoid?
