Psyco is a specializing compiler. In a few words let us first see:
|
||
|
|
|
||
|
|
What you can do with it
|
||
|
|
|
||
|
|
In short: run your existing Python software much faster, with no change in
|
||
|
|
your source.
|
||
|
|
Think of Psyco as a kind of just-in-time (JIT) compiler, a little bit like
|
||
|
|
Java's, that emit machine code on the fly instead of interpreting your Python
|
||
|
|
program step by step. The result is that your unmodified Python programs run
|
||
|
|
faster.
|
||
|
|
|
||
|
|
Benefits
|
||
|
|
2x to 100x speed-ups, typically 4x, with an unmodified Python interpreter and
|
||
|
|
unmodified source code, just a dynamically loadable C extension module.
|
||
|
|
|
||
|
|
Drawbacks
|
||
|
|
Psyco currently uses quite a lot of memory. It only runs on Intel
|
||
|
|
386-compatible processors (under any OS) right now. There are some subtle
|
||
|
|
semantic differences (i.e. bugs) with the way Python works; they should not be
|
||
|
|
apparent in most programs.
