- Worth noticing
- A 2,538 ms FT history query fell to 23 ms in an isolated copied database; the page says this is not a live-server speed multiplier.
Field notes
The page credits Terry Gerdes, AB5K, as the original author and identifies Max George, NG7M, as continuing the recovery work. It separates recovered behavior, intentional improvements, and acceptance gaps rather than presenting all work as complete. The reported upgrade comparison uses a synthetic 20,000-row fixture on the development PC, and the page cautions that this is a local directional result, not an installation-time promise.
