General Strategies for Profiling Simultaneous Asynchronous Requests


General Strategies for Profiling Simultaneous Asynchronous Requests

seems to work fine I don't know of any profiler that will be useful for this. That doesn't mean they don't exist.
I have faced this kind of problem before. I wrote a book, and discussed this in it. Basically I came up with two methods, one that works within-thread, and the other across threads. You really need both, because either one can spend time unnecessarily.

it helps some times That really depends on if it works like that properly. If the logic of the application is built that 4 simultaneos requests make sense, do it like this. If the logic isn't disturbed by packing multiple requests into one request you can do that, but only if it won't make the code more complicated. Keep it as simple and straight forward until you have problems, then you can start to optimize.
But you can ask yourself if the design of the app can be improved that there is no need for multiple requests.

I wish did fix the issue. I've set up a threaded (with Python threads) HTTP server by creating a class that inherits from HTTPServer and ThreadingMixIn:
code :
class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    pass
#!/usr/bin/env python
import sys
import urllib2

from threading import Thread

def make_request(url):
    print urllib2.urlopen(url).read()

def main():
    port = int(sys.argv[1]) if len(sys.argv) > 1 else 8000
    for _ in range(10):
        Thread(target=make_request, args=("http://localhost:%d" % port,)).start()

main()
import time
from BaseHTTPServer   import BaseHTTPRequestHandler, HTTPServer, test as _test
from SocketServer     import ThreadingMixIn


class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    pass

class SlowHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        self.send_header("Content-type", "text/plain")
        self.end_headers()

        self.wfile.write("Entered GET request handler")
        time.sleep(1)
        self.wfile.write("Sending response!")

def test(HandlerClass = SlowHandler,
         ServerClass = ThreadedHTTPServer):
    _test(HandlerClass, ServerClass)


if __name__ == '__main__':
    test()

Any of those help How can I create 2 simultaneous asynchronous requests in AngularJS having one operation that has to be done after the first request ? , You can separate the calls this way:
code :
var promiseX = $http.get('http://resourceX');
var promiseY = $http.get('http://resourceY');

promiseX.then(function(result {
    $scope.a = f(result.data);
});

$q.all({
    x: promiseX,
    y: promiseY
}).then(function(results) {
    $scope.z = g(results.x.data, results.y.data);
});

With these it helps The default behaviour on the server is to enforce sequential processing of requests for a single user session by locking the session. As such, if the first request that takes a long time to process doesn't manually unlock the session, the second request will queue up behind the first one until it completes. You likely need to call %session.Unlock() in your long-running server code.

it helps some times I had to deal with double format once as well. As you said, the only option to really have two nice layouts is to have two versions of the report - no way around that.
The easiest workaround I also used is just to go with the lowest common denominator: The size!
