How much slower is HTTPS than HTTP?

[coastal]

Hi there,

How much slower is HTTPS than HTTP? What's the best way of testing the differences?

Got a site where a user is moved back and forth and need to know whether or not I should set all links to absolute.

This would make development a touch more complex, and testing on a staging site next to impossible, but perhaps the speed gains would be worth it?

Also, does the browser recycle cached files stored from an HTTP onto an HTTPS connected page?

Thank you!

hi coastal,
i cannot really tell but i suppose the numbers of simultaneous users
on your server and the speed of your server in general will influence
the time it takes to load a site more than the protocol that is used
since httpsecure just means that a certain port (443) is used plus some
additional checks are performed... well i'm not too sure about this, never tried
it myself.

about the loading of cached formerly http delivered sites into the browser
when those sites now are delivered via https (if i got that right?):
this might be a concern of the cache's config, however, you can
influence the caching in many ways: [psychotekk.de...]

hope i could help you a bit :)

When I access my secure page from within my site, there is a noticeable slower load time. I think you are correct PsychoTekk in that the browser has call everything again via https - I know I have to code all images that way.

nice page btw
