BasicHTTPServer, SimpleHTTPServer and concurrency

I'm writing a small web server for testing purposes using python, BasicHTTPServer and Si开发者_开发百科mpleHTTPServer. It looks like it's processing one request at a time. Is there any way to make it a little faster without messing around too deeply? Basicly my code looks as the following and I'd like to keep it this simple ;)

os.chdir(webroot)
httpd = BaseHTTPServer.HTTPServer(("", port), SimpleHTTPServer.SimpleHTTPRequestHandler)
print("Serving directory %s on port %i" %(webroot, port) )
try:
 httpd.serve_forever()
except KeyboardInterrupt:
 print("Server stopped.")

You can make your own threading or forking class with a mixin inheritance from SocketServer:

import SocketServer
import BaseHTTPServer

class ThreadingHTTPServer(SocketServer.ThreadingMixIn, BaseHTTPServer.HTTPServer):
    pass

This has its limits as it doesn't use a thread pool, is limited by the GIT, etc, but it could help a little (with relatively little effort). Remember that requests will be served simultaneously by multiple threads, so be sure to put proper locking around accesses to global/shared data (unless such data's immutable after startup) done in the course of serving a request.

This SO question covers the same ground (not particularly at length).

You might also look at CherryPy -- it's pretty simple, too, and has multiple request threads with no additional effort. Although your needs may be modest now, CP has a lot of nice capabilities that may benefit you in the future.

Depending on what your requirements are, another option might be to hook in Paste. Though, based on your example, it may be overkill. Something to keep in the toolbox.
