Or the better solution is to fix your resolver.

Re: intervall of about 1 second for xmlrpc calls?

[rav]

I had similar problem with SimpleXMLRPCServer
Create the request handler class

class ExtendedXMLRPCRequestHandler(SimpleXMLRPCRequestHandler):
# originally this one was slowing down my server A LOT due to DNS
settings!!!
def log_request(self, *args):
pass

and put it in your SimpleXMLRPCServer constructor

(...)

class MyServer(threading.Thread):
def __init__(self, host, port):
threading.Thread.__init__(self)
self.server = SimpleXMLRPCServer((host, port),
ExtendedXMLRPCRequestHandler)
self.server.register_function(self.is_even, "is_even")
self.server.register_function(self.stop, "stop_server")

(...)

I would also change all 'localhost' occurences in the code to ip
'127.0.0.1'.

Good luck!

No.  This would seem to have something to do with the resolver.  If you
do a nslookup for localhost what does it say.

Have lots, it's really nice.  Once you get most things cut over.

Does nslookup localhost return the correct result?  That might depend on
your DNS server - not your local host.

Also "ping ::1"?

I think you're right.

localhost  with IPV6 was also a problem for me. At least it was for me
on a windows 7 host.
I 'solved' the problem by disabling IPV6, but this is a workaround, not
a proper solution.

Do you know why the default config of IPV6 could be wrong on a windows
7 host?

Having no experience with IPV6:

How should it be configured?
How to detect issues?


thanks

You box may first be trying to connect to ::1 (ipv6) and when that fails
it falls back to 127.0.0.1.  Make sure IPv6 is properly
configured/enabled and try the script again.

Obviously there's a problem with "localhost". When using the IP of my
machine everything is working fast.
