// a single instance

// grab an instance of our connection pool
SockIOPool pool = SockIOPool.getInstance();

// set the servers and the weights
pool.setServers(servers);

// set some basic pool settings
// 5 initial, 5 min, and 250 max conns
// and set the max idle time for a conn
// to 6 hours
pool.setInitConn(5);
pool.setMinConn(5);
pool.setMaxConn(250);

// set the sleep for the maint thread
// it will wake up every x seconds and
// maintain the pool size
pool.setMaintSleep(30);

// set some TCP settings
// disable nagle
// set the read timeout to 3 secs
// and don’t set a connect timeout
pool.setNagle(false);
pool.setSocketTO(3000);
pool.setSocketConnectTO(0);

// initialize the connection pool
pool.initialize();

// lets set some compression on for the client
// compress anything larger than 64k

}

// from here on down, you can call any of the client calls
