Is it possible that a cheap security certificate could inhibit the performance of a website when serving pages over https?
Background: I have built an e-commerce website using Drupal 7 and Drupal Commerce. The site runs on an m3.xlarge Amazon EC2 Instance and everything has been performing very fast and efficiently until last weekend.
Last weekend saw a large spike in traffic over normal levels (bank holiday weekend), which saw up to 50 concurrent users on the site . The non-secured pages performed fast, however, when a user went from a
http page (eg: the basket page) to a secured
https page (checkout page), the site became very slow and in some cases crashed. As a test, removing the switch to
https maintained the performance of the site and got it back up and running.
- Could the cheap SSL certificate have a hand in this issue?
- Are there advantages in speed depending on the type of certificate purchased?
- Does it sound like it could be an Apache configuration error?
