Hi Rushikesh, There is no update of documents in Solr - it is always indexing a new document to a new segment. That means that indexing operation is equally heavy on any collection. But that does not mean that updates will take equal time. There are other activities that are heavier on larger indices like commits and segment merges that can prevent updates to be visible or can exhaust resources so that indexing new document takes longer. You will usually indexing throughput going down as index size goes up.
