Slow backtesting?

["Gary Fritz" <fritz@xxxxxxxx>]

I'm running into some odd behavior in backtesting.  In my experience, 
backtest runs always run at about the same speed as if I wasn't 
optimizing.  I.e. if the system takes 4 seconds to run when I just 
apply it to the chart with fixed values, then I expect every test run 
in the optimization will also take 4 seconds.

I'm trying to backtest a system on an ASCII file of daily data.  When 
I first apply the system, or if I change any given parameter, the 
system runs in about 2-3 seconds.  But in an optimization run, each 
test is running for over 2 minutes!

Any guesses what's going on here?
