Web requests in Python

abgoswam python, webtechnologies

Recently tried making web requests in Python.

I used the urllib2 library for making 10 requests to the Azure Machine Learning web service.

Interestingly I found that using urllib2  was incurring a lot of latency.   I replaced urllib2 with the requests libarary and boom, the latency improved tremendously.

Tip:

  • it seems the requests library  by default uses KeepAlive.  As such, it was not re-initiating the connection each time for the multiple requests. urllib2 on the other hand was re-initiating the connection for each request.
  • Note:  the requests library is still making synchronous calls.
