I work on a site with a long history. I recently created a benchmark and found that I could make around 500 synchronous HTTP requests to our infrastructure per second (essentially localhost calls). If I switch my benchmark to HTTPS I can only make about 5.<p>That&#x27;s a big difference. I&#x27;m a developer, not a hardware guy, so I don&#x27;t know what causes the slowdown for us. I assume it&#x27;s the actual setup and teardown of the HTTPS connection.  That is a fairly significant difference when I want to use API&#x27;s via HTTP&#x2F;HTTPS and I need to make a lot of calls quickly.<p>My point is that HTTPS still seems to be 100x more computationally expensive than HTTP.
