Package: apt-cacher
Version: 1.6.8
Severity: normal
apt-cacher-cleanup.pl reads:
387: my ($zip,$encoding) = ($name=~/bz2$/ ? ("bzip2","x-bzip2") :
($name=~/gz$/ ? ("gzip -9nc","x-gzip") : "cat"));
The compression level -9 is overkill and too heavy for old hardware. A better
compression
level would be -3. See effects of various compression levels e.g. at:
"Practical Compressor Test"

results
-------
The -9 vs. -3 in the tests were 13.3 seconds vs. 3.2 seconds (10x),
where compression gain was neglible in higher levels.
In contrast bzip2 -1 took *18.4* seconds.

I have not heard anything else which makes me think this is a real bug,
so closing.
