Hi, Maybe you can narrow this down a little further. Are there some queries that are faster and some slower? Is there a pattern? Can you share examples of slow queries? Have you tried &debugQuery=true? These 3 shards.... is each of them on its own server or? Is the slow one always the one that hits the biggest shard? Do they hold the same type of data? How come their sizes are so different?
