when you have your site running for long time none ssl
and change site to full ssl
it then try change the whole database to https and maxed out connection
that send cpu through the roof
i have 2 sites one use heaps cpu and memory try change everything to ssl
but as the cpu is high both site throw enternal server error
but other scripts on both domains still open
but time from 3 seconds to 20 seconds to open due to the high cpu and memory usage
i can understand the site use so much cpu and smashing the database throw error
but the other site should run but run slow
