Title: Low bandwidth: Fetch OpenBSD sources Author: Solène Date: 09 November 2017 Tags: openbsd70 openbsd versioning Description: When 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.
