urllib2 and requests were about the same speed as urllib.urlretrieve,
while pycurl was significantly slower (1.2 seconds).
Network access is notoriously erratic in its timing. The program, and
the machine on which it runs, is subject to a great many external
effects once the request is sent — effects which will significantly
alter the delay before a response is completed.
How have you controlled for the wide variability in the duration, for
even a given request by the *same code on the same machine*, at
different points in time?
One simple way to do that: Run the exact same test many times (say,
10 000 or so) on the same machine, and then compute the average of all
the durations.
Do the same for each different program, and then you may have more
meaningfully comparable measurements.
I tried the 10-loop test several times with all versions.
The results were 100% consistent: VBSCript xmlHTTP was always 2x faster
than any python method.
