| 35 | | -Every read of git data is a call out to the plumbing with a thirty second timeout, which in practice means `ls-tree -l` for trees and `log` with a NUL separated format for history and `diff-tree -p --root -M` for commit pages and `cat-file` for blobs. Nothing is parsed out of packfiles in process, so a large repository costs exactly what git says it costs. A buffered call that tries to return more than 16 MiB gets killed. Only twice the core count may run together, or four on a single core box, and raw files and archives stream two at a time. On git.vm.fail the server idles at about 35 MB resident, so most of a 512 MB VPS is left for git. |

| 37 | 37 | A little is remembered between requests, though deleting all of it loses nothing. Language bars and the history behind the activity graph are stored against the mtime of the refs, so after a push one `stat` notices and before one nothing is read at all. That history holds sixteen bytes a commit (a hash prefix, the day and which author address it was), and the list of people that search walks is refreshed at most twice a minute. |
