[Pyparsing] parsing with operatorPrecedence takes too much time

[Ralf S. <sc...@gm...>]

Hi all,

I'm attaching a short test program that tries to parse mathematical
expressions using operatorPrecedence.
It takes nearly one second to parse a simple expression like 1+1+1-(5+2) (on
a 2.4Ghz machine).

Any hints? Am I doing something wrong?

Regards,
