I'm a denizen of the solr-user at lucene.apache.org mailing list.

For a typical Solr index, 60 seconds is an eternity.  Most people aim 
for query times of 100 milliseconds or less, and they often achieve that 
goal.

If you have an index where queries really are taking longer than 60 
seconds, you're most likely going to need to get better hardware for 
Solr.  Memory is the resource that usually has the greatest impact on 
Solr performance.  Putting the index on SSD can help, but memory will 
help more.

Here's a wiki page that I wrote about that topic.  This wiki is going 
away next month, but for now you can still access it:

https://wiki.apache.org/solr/SolrPerformanceProblems

There's a section in that wiki page about asking for help on performance 
issues.  It describes how to create a particular process listing for a 
screenshot.  If you can get that screenshot and share it using a file 
sharing site (dropbox is usually a good choice), I may be able to offer 
some insight.

Thanks,
