Forum loads slow after hitting Latest, New and Unread for the second time

Our forum loads fast when opening it, visiting topics and hitting the top menu items (New, Unread, etc.) for the first time. But after hitting the menu items, except Categories, it will load slow.

I have disabled all plugins, then enabled them one by one, removed some plugins and rebuild the forum, but the issue persists.

Does anyone have another tip I can try?

Related to this I suspect?

Np appears to occur here on Meta so looks like a core bug?
