Public bug reported:
current orchestra squid configuration has:
| acl PACKAGES url_regex \/Packages(|\.bz2|\.gz)$
| cache deny PACKAGES
| acl SOURCES url_regex \/Sources(|\.bz2|\.gz)$
| cache deny SOURCES
| acl RELEASE url_regex \/Release(|\.gpg)$
| cache deny RELEASE
That means that those files are *never* cached, meaning each client
request guarantees a non-local network operation.
Currently, amd64 'apt-get update' would report:
Fetched 22.2 MB in 35s (618 kB/s)
So, thats 22MB that will never be cached.
The suggested fix is to use 'refresh_pattern' instead of deny, with a
basic diff then looking something like:
