title: Jira -Python update issues takes very long time
body: <p>I am using python with jira package and writing a simple script that will create or update all the existing issues for a project on my company's server.
  Creating multiple issues via python is very fast and i can create 100 issues within 30 or seconds. But the problem is when i want to update those issues. When i update issues it takes a very long time probably 4 or 5 minutes for updating 100 issues. I am getting the <strong>InsecureRequestWarnings</strong> warning. I tried to disable warnings as well but still the program is very slow when it comes to updating the issues. How can i make updating issues faster?
  NOTE: Each issue update takes more than 3.1 secs.</p>
