34. 34. Server::Starter • "a superdaemon for hot-deploying server programs" • Gracefull restart(hot-deploying) • Only exit old process if new process is successfully booted.(safe!) • No resource leak
35. 35. Requirements a (your) server program. • Support Gracefull shutdown • Use socket FD passed from server starter to app
36. 36. usage (with Starman) start_server --interval 5 --port 8000 --signal-on-hup=QUIT # for Starman -- starman --preload-app myapp.psgi • start_server command will install when install Server::Starter.

57. 57. why not LWP?? • "Why does it need to be faster ?" • "because, we are japanese !!!!" Ofcourse, we need that.
