Re: [Jython-users] slow overloaded method

[Jeff E. <jem...@fr...>]

I ran your test on Windows, and it is still slow, so it is not a Mac problem.
I don't know the reason it is so slow, but I noticed that in old versions of Jython (2.1 and 2.2),
your script takes about 5 seconds instead of 60.

If you change your script to create a 4D array explicitly, then it runs much faster.
This ran in about 1ms for me, which is the same time as without the overloaded 3D array
method.

import time,TestClass
n1,n2,n3 = 250,250,250
z = TestClass.zeros(n1,n2,n3)

import java,jarray
z4d = jarray.array([z,z,z],java.lang.Class.forName('[[[F'))

start = time.time()
TestClass.overloaded(z4d)
print 'time =',(time.time()-start)
