[Zope] External Method = Slow; Shell Script = Fast

[Edward Pollard]

Hello,

I've got an external method that does some pretty complicated stuff.
Basically it takes two XML files - one defines constraints, the other
variables - and the script finds a solution using the variables that
satisfies the constraints.

At the command line (or executed via an external method that calls a shell
script) execution is 2 seconds.

As an external method execution is 15-20 seconds with the same input.

Can anyone offer tips or strategies to improve performance? It would be
obnoxious to have to encode objects for passing to a shell script.
