NILWhen you fetch OpenBSD src or ports from CVS and that you want to save

bandwidth during the process there is a **little** trick that change

everything: **compression**

Just add `-z9` to the parameter of your cvs command line and the

remote server will send you compressed files, saving 10 times the

bandwidth, or speeding up 10 times the transfer, or both (I'm in the

case where I have differents users on my network and I'm limiting my

incoming bandwidth so other people can have bandwidth too so it is

important to reduce the packets transffered if possible).

The command line should looks like:

$ cvs -z9 -qd anoncvs@anoncvs.fr.openbsd.org:/cvs checkout -P src

Don't abuse this, this consumes CPU on the mirror.
