In our existing distributed indexer cluster we have systems with slightly different configurations(storage and some slight hardware differences). I'm trying to determine if there is any difference in performance being seen by Splunk across each of these systems related to typical indexer functionality. Is there a way to measure the performance of each indexer in the existing environment for comparison?
https://splunkbase.splunk.com/app/3002 can show you if the system itself is performing well.
Other than that and the DMC (as mentioned by @gpradeepkumarreddy) you'll want to explore the Job Inspector to see the load per indexer and normalize with events/second: http://docs.splunk.com/Documentation/Splunk/latest/Search/ViewsearchjobpropertieswiththeJobInspector

Start with DMC App. It has several views related to indexing performance
