[reportlab-users] PDF Generation performance

[Karl Putland]

A couple of years ago I sent a case study to Andy that contained
performance numbers for a HUGE report I used to run.  I'll see if I can
find it.  Maybe Andy has it laying around somewhere.  It's been a while
and I don't know if I've still got it.
