Question

Here is what I\'m trying to do: I\'m developing a Node.js http server, which will hold long connections for pushing purpose(collaborate with redis) from tens of thousands of mob

Answer 1

Just a few notes:

Do you need to wrap res in an object {res: res} can you just assign it directly

pendingClinets[req.clientId] = res;

EDIT another ~micro optimization that might help

server.emit('request', req, res);

passes two arguments to 'request', but your request handler really only needs the response 'res'.

res['clientId'] = 'whatever';
server.emit('request', res);

while your amount of actual data remains the same, having 1 less argument in the 'request' handlers arguments list will save you a reference pointer (a few bytes). But a few bytes when you are processing hundreds of thousands of connections can add up. You'll also save the minor cpu overhead of processing the extra argument on the emit call.
