Not only is there a profiler, there's benchmarks!

Maybe you could add one for twisted.web.template rendering speed?

Thanks for the thought, at least. Cross-posted.

Hi!
I'm thinking about using Twisted as a http client, talking to some
rather uncooperative servers that sit on the other side of some really
crappy parts of the internet. So I need timeouts.
I was looking into t.w.c.Agent, and see that it has a connect timeout
option, which is good, but lacks request timeouts. Then found
http://twistedmatrix.com/trac/ticket/4330 which looks like a solution.
I'm a little confused on how to use #4330. Would something like this be
appropriate:
def main():
agent = Agent(reactor)
deferred = agent.request('HEAD', url)
cancel = reactor.callLater(30, deferred.cancel)
deferred.addCallback(handle_request)
deferred.addErrback(handle_errors)
def handle_request(response):
cancel.cancel()
<handle response>
def handle_errors(failure):
<see if failure is CanceledError>
Will this also automatically give me a connection timeout, or should I
give Agent's constructor connectTimeout as argument and handle that in
handle_errors too?
I might have totally misunderstood the whole thing too, as I'm a bit new
to Twisted.
Thanks,
\EF
I want to implement a protocol for FCGI twisted.web. Search did not
help me. It may already have an implementation? If nothing like this,
i will continue its implementation.
