Psyco on PowerPC?

[Benjamin Han]

Ok here is what I did

1. pulled the latest CVS
2. did a "python setup.py install"
3. ran this testing program:

-- CUT --
#!/usr/bin/env python

import time
import psyco

def f (x):
    p1=p2=ret=0
    for i in xrange(0,x+1):
        if i==1:
            p1=ret=1
        else:
            ret=p2+p1
            p2=p1
            p1=ret

    return ret

startTime=time.time()
print f(100000)
endTime=time.time()
print '* Elapsed time =',endTime-startTime

fastF=psyco.proxy(f)
startTime=time.time()
print fastF(99)
endTime=time.time()
print '* Elapsed time =',endTime-startTime
-- CUT --

The result (on my PowerBook G4):

2597406.... (big number)
* Elapsed time = 2.41602706909
Fatal Python error: psyco: out of memory
Abort trap


I have 1 GB memory. Maybe it's still in the early development stage?

Thanks,

Ben
