README

        
Adds some I/O timing metrics to solr so you can evaluate your disk performance. 

Only works for NIOFSDirectory (non-Windows systems). 

Build project.

Add jar file to solr/lib.

Add elements to solrconfig:

    

    

    

Run Solr.

Open:

/dirStats

to see I/O timing information. 

Open:

/dirStats?reset=true

to reset stats.

This wraps readInternal() call in NIOFSDirectory in lucene. I believe this will end up capturing all the bytes read from disk and the amount of time spent reading these bytes.
