Why after you add certificates to the browser, it starts to slow down?

I had to add 10 certificates in browsers (Chrome and Firefox). It was necessary for one system online identification.
Purely visually -then the opening pages began to slow down in both browsers.
Why can this be? Maybe the browser tries to check the validity of certificates? no idea what was going on under the hood.
