I released Gazelle, new Plack handler

Gazelle - Preforked Plack Handler for performance freaks - metacpan.org

Gazelle is a Plack Handler/PSGI server. This server is optimized for running HTTP application server behind a reverse proxy like nginx. When start Gazelle behind nginx and connect via unix domain socket, Gazelle is 3 times faster than starman.
