Reduced image size with no apparent reduction

RE: Reduced image size with no apparent reduction
Remember that download time is not linearly related to file size. What you are interested in is the number of tcp round trips - which will, of course, depend where the requests are in the tcp slow start cycle.

As a for instance, I have a 120kB background image which last time I measured it came down in the following numbers of packets on a new connection:

3, 5, 8, 12, 21, 37

i.e. 6 round trips. To get it down to 5 round trips i.e. only a 1/6 improvement, I would have to reduce the size by 37/88.
