Hello,
Thank you for your reply.
I too have done some tinkering. I disabled all the plug-ins and also swapped from X11 to Wayland. Although I prefer X11 because it supports KDocker, Wayland yielded more of a response when typing to the point where the lag is negligible.
Logseq still takes a minute of so to load, but I do have over 2,500 pages(?) to load and index, so I happy to set it off in the morning and go and make a cup of tea.
Regards
Richard
