Update: * we removed the materialized page cache https://github.com/neondatabase/neon/pull/8105 * the remaining data pages that are still in the PageCache is the InMemoryLayer pages * starting point for investigation: [this...

This time range here is instructive: in this time range, there is a high access rate coming from `LayerFlushTask` for InMemoryLayers which is displacing DeltaLayerBtreeNode layers which causes cache misses...

If it's just the LayerFlushTask perhaps this is the time to implement * https://github.com/neondatabase/neon/issues/7418

This week: * merge & benchmark https://github.com/neondatabase/neon/issues/7418 * start working on https://github.com/neondatabase/neon/issues/8183

Status update: * gradually rolling into prod: https://github.com/neondatabase/neon/issues/7418 * scouted https://github.com/neondatabase/neon/issues/8183 * seems like it's better done after https://github.com/neondatabase/neon/issues/8184 * https://github.com/neondatabase/neon/issues/8184 * coding done * validation in staging, will build...
