ruby-net-http-persistent 2.9-3 (amd64 binary) in ubuntu wily

 This package provides persistent connections to Net::HTTP.
 .
 Creating a new HTTP connection for every request involves an extra TCP
 round-trip and causes TCP congestion avoidance negotiation to start over.
 Using persistent HTTP connections can dramatically increase the speed of HTTP.
 .
 Net::HTTP supports persistent connections with some API methods but does not
 handle reconnection gracefully. Net::HTTP::Persistent supports reconnection
 and retry according to RFC 2616.
