+README for Plack FCGI interface for LedgerSMB
+Chris Travers
+2012-11-13
+----------------
+
+This addon provides an app.psgi for LedgerSMB which allows you to properly run
+servelets as fcgi scripts instead of as CGI scripts.  This makes LedgerSMB
+significantly more responsive but performance is more difficult to manage under
+load.
+
+The current module preloads a fair number of modules and then runs a
+fork/wait/execute loop where the less safe code is run.  This performs well on
+platforms which provide copy on write functionality, but may not perform as well
+on Windows.  The startup overhead for the dependencies is thus limited in this
+case to a one-time load on starting the servelet.  Tests suggest that this
+eliminates 2/3 or more of the startup overhead.
+
+By default this currently starts up to 10 processes.  This number can be
+tweaked.
+
+To run the servelet, you will need to run the following from a startup script
+somewhere:
+
+plackup -s FCGI -D --listen /var/run/httpd/fastcgi/lsmb.sock
+
+
