Why does search speed suffer (and RAM consumption increases) when there are a large number of vectors in Weaviate?

Hi @DevelMyCry,

Have you upgraded to Weaviate version 1.28.2 to see if it offers any performance improvements?

Do you have multiple nodes setup right? Furthermore, it might not be direct but have you tried to set ef to dynamic ef = -1?

Hope this helps!
