XF 2.1 What's New / New Posts / Recent Posts slow since upgrade (for one forum member) - 7s delay

[CycleChat]

See screenshot below - it's taking 7 seconds to serve "posts/" for one specific forum member.

Any idea what's happening and how to resolve it?

Thanks

Member reports that when they log out New Posts runs fast. Log in again, goes slow.

Try disabling all add-on and see if that corrects the issue.
