Ruby GServer performance

Question

I tested the performance of GServer by implementing the most basic server and checked how many requests per second it could handle. The result was 81. This is very slow compared to the 9900 requests per second that my most basic TCPSocket server can handle. Am I doing something wrong or is GServer really this slow?

Client
require 'socket'
tStart = Time.now
u = 0
while Time.now - tStart<5
socket = TCPSocket.open('localhost', 1234)
socket.puts 'a'
socket.gets
socket.close
u += 1
end
puts u.to_s

GServer implementation:
require 'gserver'
class JServer < GServer
def initialize(args)
super(args)
end

def serve( io )  
    io.gets  
    io.puts( 'a' )  
end

end
server = JServer.new(1234)
server.start
loop { break if server.stopped? }

TCPSocket server impl:
require 'socket'
server = TCPServer.open(1234)
loop {
client = server.accept
puts client.gets
client.puts( 'a' )
client.close
}

Answer 1

You should get a significant speedup (approximately 30x from my testing) by replacing

loop { break if server.stopped? }

with

server.join

That being said, GServer uses threads and will probably be slower than a single-threaded event-based server.
