[Python-Dev] FW: Program very slow to finish

I don't think so. Tuning malloc is only possible if you know the
access pattern, and if you can experiment. E.g. in an MT application,
those parameter may need completely different values from the ones in
a single-threaded application. Or, an application allocating many
strings might have different requirements than an application
allocating many numbers (which are fixed-size).

These parameters are offered to applications, to quiet the application
developers that have been asking for them all these years, without
knowing what they'd get when they can tune the parameters. If you
don't know the application (such as when implementing a Python
interpreter), they are useless.

As will all computational-complexity problems: You can change the
constants. You cannot change the complexity class of an algorithm with
tuning.
