Hi,
I didn't have any buffering size set before, so I believe it defaults to 0 (no
buffering), right? Wouldn't this be the behaviour on both 2.x and 3.x?
I'm using a 1.5 Mb bzip2 file - I just tried setting buffering to 1000 and
1000000, and it didn't seem to make any noticeable difference to the speed of
reading in the file. E.g.:
f = bz2.BZ2File(filename, 'rb', buffering=1000000)
What sort of values did you use in relation to your compressed file size to get
the improvements?
Cheers,
Victor
