bz2.readline() slow ?

P: n/a
Dear all,

I am a bit puzzled, as

import bz2

while f.readline():

takes twice the time (10 seconds) to read/decode a bz2 file
compared to

import bz2

(5 seconds). This is even more strange as the help(bz2) says:

| readlines(...)
| readlines([size]) -list
| Call readline() repeatedly and return a list of lines read.
| The optional size argument, if given, is an approximate bound on the
| total number of bytes in the lines returned.

This happens on python2.3 - python2.5 and it does not help to specify a
maximum line size.

Any ideas ?
