Re: CALLP vs CALLB vs EXSR

["David Shea" <dshea@xxxxxxxxxxxx>]

I did some tinkering with CALLB vs CALLP related to a web application.  All
I can tell you is before, using CALLP, the response time to get the page up
was 15 seconds or more.  After changing to CALLB, response time dropped to 5
seconds or less.  I don't know just what the he*& was going on with the
difference between callp and callb, but it sure made a HUGE improvement.
