I have a Python program that runs too slow for some inputs. I would
like to speed it up without rewriting any code. Psyco seemed like
exactly what I need, until I saw that it only works on a 32-bit
architecture. I work in an environment of Sun Ultras that are all 64-
bit. However, the Psyco docs say this:

"Psyco does not support the 64-bit x86 architecture, unless you have a
Python compiled in 32-bit compatibility mode."

Would it make sense to compile Python in the 32-bit compatibility mode
so I can use Psyco? What would I lose in that mode, if anything?
Thanks.

Has anyone tried this?

Isn't the SUN Ultra using an ULTRA-Sparc core? If so, the point is moot.

No, it's Intel based.

I just stumbled across "unladen swallow," a "faster implementation of
Python." Is it ready for operational usage? How does it compare to
Psyco? I poked around their website a bit, but I don't see answers to
those questions. Thanks.
