way you're doing it now costs more time and memory. More time, because you
first read int eh whole file from disk, before you start outputing, while if
you do this at the same time you will safe some time. Memory will saved, as you
do not need to keep the whole file in memory, but only the part which you load
in buffer.
I totally agree. I was just wondering if someone could venture a guess
as to how much of a performance hit doing it the current way vs. what
you suggest is.
The reason I ask is that I don't want to fix it (i.e. implement your
solution) if all I will get is a 5% performance improvement. I'm in need
of a >2x performance benefit :(
