Tip: Mercurial atop ssh
On opensolaris.org, we host Mercurial and Subversion via their ability to tunnel through an SSH connection. A slight gotcha with Mercurial is that it turns off compression when tunnelled through SSH, as described in
$ man hg .... - Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your ~/.ssh/ssh_config, e.g.: Host *.mylocalnetwork.example.com Compression off Host * Compression on Alternatively specify "ssh -C" as your ssh command in your hgrc or with the --ssh command line option. ....
For pulls of a large repository, such as ON, compression changes an approximately 51 minute operation to a 17 minute operation. So you’ll want something like
$ cat ~/.ssh/config …. Host hg.opensolaris.org Compression yes … ….in your SSH configuration.
