Yes they are rpm's but: the header (*.hdr) files and many RPM (*rpm)
files can be compressed to save space and bandwidth.
There are some "httpd" (apache) web server tricks involving
compression that may come to play here. I just did a quick look at
the compression ratios on *.hdr files and see some interesting
numbers.
For headers the worst were
46.5% 47.4% 47.6% 47.8% 47.9% 48.0%
and the best were
74.6% 74.7% 74.8% 75.4% 76.1% 78.9%
I saw two ringers at 84% and 95% that I do not believe and want to check.
As for the rpm update packages I see compression ratios
that run from the expected:
-0.0% 0.0% 0.0% 0.0% 0.0% 0.1% 0.1% 0.1% 0.1% 0.1% 0.1%
to the unexpected:
34.4% 43.3% 44.5% 45.2% 45.9% 46.7% 48.2% 58.7% 59.1%
This tells me that a responsible archiving web site manager would be
using all the compression tricks at his or her disposal to our
advantage.
