That is to be expected. Non-logged-in pages can be cached aggressively server side. When you are logged in much more has to be done dynamically.
The fact that non-logged-in pages are still loading fast is testament to the fact that the HN devs have done their job properly with implementing caching.
In the bad old days it would be slow for everyone whether logged in or not. In general I mean. I have only been on HN since 2009 and have been logged in (other accounts in the past, changed name) pretty much always so I don't know when HN got good at caching. I would kind of sort of expect that HN was actually like that from the beginning, given that pg came from having used Lisp in production at Viaweb and they got a lot of experience there early at how to do things fast (in terms of time to implement) and presumably proper (since they were able to compete with others).
