+# Sample verbose configuration file for Unicorn (not Rack)
+#
+# This configuration file documents many features of Unicorn
+# that may not be needed for some applications. See
+# http://unicorn.bogomips.org/examples/unicorn.conf.minimal.rb
+# for a much simpler configuration file.
+#
+# See http://unicorn.bogomips.org/Unicorn/Configurator.html for complete
+# documentation.
+
+# Use at least one worker per core if you're on a dedicated server,
+# more will usually help for _short_ waits on databases/caches.
+worker_processes 2
+
+# Since Unicorn is never exposed to outside clients, it does not need to
+# run on the standard HTTP port (80), there is no reason to start Unicorn
+# as root unless it's from system init scripts.
+# If running the master process as root and the workers as an unprivileged
+# user, do this to switch euid/egid in the workers (also chowns logs):
+# user "unprivileged_user", "unprivileged_group"
+
+# Help ensure your application will always spawn in the symlinked
+# "current" directory that Capistrano sets up.
