Sorry, the title of the issue isn't correct any more. The revised
issue is that in 3.3

a) outfil.write("%s\n" % t)

is about 11% slower than in Python2.7 and 8% slower than in Python3.2.


On the other hand in 3.3 the hack

b) outfil.write(str(t)); outfil.write('\n') 

runs about as fast as a) in 3.2.


This doesn't necessarily show up in microbenchmarks with timeit, so
I thought I'd leave this open for others to see (and comment).

But if I understand correctly, the slowdown in string formatting is
expected, so we can indeed close this.
