Is that why Python3 slower than Python2?

I have a simple test.

OS: Windows7 32bit

# test.py

import time

if __name__ == '__main__':
    stratTime = time.time()
    f = open("D:\test.log", 'r')
    w = open("temp.txt", 'a');

    while True:
        line = f.readline()
        if not line: break
        temp = line.split('-')
        w.write(temp[1])

    f.close()
    w.close()

    print time.time() - stratTime

test.log is BigFile.
The line number of test.log is 1487573

SimpleTest Result
Python2.7: 3.5
Python3.3: 9.1

Why the above results?
