The load can get rather high: 1. poudriere for a desktop, so lots of ports 2. poudriere will eat swap with a bulk run with the larger ports. I've watched it run out of swap then the OS killed the running processes 3. the OS is on the ssd and data (including poudriere) run on zfs. >> Doesn't swap need to be 2x RAM on a fast disk? > >No, this is really an old assumption. OK, but doesn't it need to be at least the size of RAM if for example a panic happens? I thought the contents of RAM were written to swap. -- J.
