Hi Xin, I don't know if you can see this information anywhere in Solr's UI... ... but I know you could see this information using SPM for Solr [1]. I don't have a screenshot handy to show this visually, but it's easy to explain. One of the SPM for Solr reports shows the index size (in terms of size on disk, number of files, number of segments, number of documents, etc.). You can see how this size changes over time [2], so if you look at this report before and after replication, you will see how much your index size changed after replication and will know how much data was replicated. And since there is also a report that shows query response time, you will be able to visually see how much faster or slower query performance is after replication.
I hope this helps.
