About
Socket#set_accept_filter allows you to enable accept filters on server sockets.
In FreeBSD accept filters allow you to delay the return from an accept() call until enough data arrives on the connection for processing avoiding extra context switches while waiting for the missing data.
Consult the accf_data(9), accf_http(9) and accept_filter(9) man pages for further details.
Installing socket_accept_filter
Run FreeBSD (or any BSD, I think).
Then install the gem:
$ sudo gem install socket_accept_filter
Using socket_accept_filter
Regular sockets
require 'rubygems'
require 'socket'
require 'socket_accept_filter'
server = TCPServer.new host, port
server.set_accept_filter 'dataready'
Then use the server socket as you would ordinarily.
WEBrick
require 'rubygems'
require 'socket'
require 'socket_accept_filter'
require 'webrick'
class MyServer < WEBrick::HTTPServer
def listen(*args)
super
@listeners.each do |server|
server.set_accept_filter 'httpready'
end
end
end
Then use MyServer where you would ordinarily use WEBrick::HTTPServer.
