file seek is slow

[Metalone]

I just tried the seek test with Cython.
Cython fseek() : 1.059 seconds.  30% slower than 'C'
Python f.seek  : 1.458 secondds. 80% slower than 'C'.

It is amazing to me that Cython generates a 'C' file that is 1478
lines.


#Cython code

import time

cdef int SEEK_SET = 0

cdef extern from "stdio.h":
    void* fopen(char* filename, char* mode)
    int fseek(void*, long, int)

def main():
    cdef void* f1 = fopen('video.txt', 'rb')
    cdef int i=1000000
    t0 = time.clock()
    while i > 0:
       fseek(f1, 0, SEEK_SET)
       i -= 1
    delta = time.clock() - t0
    print "%.3f" % delta

if __name__ == '__main__':
    main()
