After installing and using a self-signed SSL certificate by following the official guide here and running our test suites it was discovered that the tests take about 3 times as long. I would expect there to maybe be some sort of delay but that's a lot.

Any ideas on why this is the case?

With SSL: 45 passed (6m 56s)

Without SSL: 45 passed (2m 55s)
