one additional change might get quite some more speed.

def filterfile2(inname, outname):
     localint = int
     out = file(outname, 'w')
     for line in file(inname):
         x, y, z = line.split()
         sum = localint(x) + localint(y) + localint(z)
         print >>out, line, sum

ps: i'm new to python and have just fallen in love with the language. 3 
cheers to everyone who's a part of the team including all the people in 
this group who are very helpful.
