So would this also apply to older zopes? Like 2.7.5?? Exactly where is that changed and in what increments are safe to increase it by?

Thanks

Allen

- Tune the ZEO disk cache size (the warning sign is seen lots of
  "ZEO cache flip" entries in the event log).


Can you explain this some more?

1. Do we increase the cache size when we see these ZEO cache flips?


Yes  In general, keep increasing it until they are no longer "noticeable".


2. What is a "good" rate for these cache flips?


I don't have a firm sense, but no oftener than every hour, say:  when
the cache flips, you lose half the working set (the "oldest" half).
