What does “PERFORMANCE WARNING: Overlapping onDeckSearchers=X” mean in my logs?
This warning means that at least one searcher hadn’t yet finished warming in the background, when a commit was issued and another searcher started warming. This can not only eat up a lot of ram (as multiple on deck searches warm caches simultaneously) but it can can create a feedback cycle, since the more searchers warming in parallel means each searcher might take longer to warm.
