asyncio + uvloop echo server benchmark

This is an attempt at a bare minimum client/server benchmark of asyncio with optional use of uvloop. On my 2015 macbook pro, I get almost 2.5X improvement using uvloop in the server.

The client runs PARALLEL tasks at once. Running only a single task results in about 1/8 the throughput of 100 simultaneous tasks.

# with uvloop
$ python client.py
satisfied 100000 requests in 1.41021 seconds (70911.42 reqs/s)

A response to Preetam Jinka's nice little Go demo.

Similar basic HTTP server using Gevent/Python

from gevent import pywsgi
import md5

def md5_body(environ, start_response):
    md5Hash = md5.new()

Cześć!

Hello and thanks for being a part of my presentation. Below is a list of links that are pertinent to the presentation on May 14th, 2014 at Open Source Days in beautiful Warsaw, Poland.

Feel free to take a look at these links before, during, or after my presentation.

If you would like to contact me at any time to talk about this presentation or others I have given, you can find me at the following places:

This example pulls together various examples of work with trees in D3.js.

The panning functionality can certainly be improved in my opinion and I would be thrilled to see better solutions contributed.

One can do all manner of housekeeping or server related calls on the drop event to manage a remote tree dataset for example.

Dragging can be performed on any node other than root (flare). Dropping can be done on any node.

Panning can either be done by dragging an empty part of the SVG around or dragging a node towards an edge.
