Paul; could you please make this your current priority, to explore why the wiki is so slow and what we should do about it?
Okay then!
I identified the hitcounter as a possible problem. It is used by the <<Hits>> macro and by the statistics subpage for every page. The only page using the macro was the sandbox of my own user page (that is how I got suspicious the first time). The statistics subpages (Info -> Show "Page hits and edits") seem to be rarely clicked by humans but are regularly indexed by search engines.
- I disabled the statistics pages using a rewrite rule - I disabled the macro by unsetting the read permission of /opt/moin-1.9.8/MoinMoin/macro/Hits.py - Independently from this I installed fail2ban which by default is active for ssh
I had a look into the source code of moin-1.9.9 and the problem does not yet seem fixed there (although the devs seem to be aware that the corresponding code needs an overhaul).
Funny thing: I do not experience the lag in everyday use (maybe two or three seconds max, sometimes when editing a page). Maybe you could keep an eye out for the pages and actions that immediately lead to larger delays.
I will try to keep an eye out too. Please let me know, if my changes did not yet do the trick.
