OK, so to test indexing performance, there are no caches to worry
about (as long as you have autowarmCount=0 on all caches, as is the
case with the Solr example configs).

To test sorted query performance (I assume you're sorting the index to
accelerate certain sorted queries), if you can't make the queries
unique, then add
{!cache=false} to the query
example: q={!cache=false}*:*
You could also add a random term on a non-existent field to change the
query and prevent unwanted caching...
example: q=*:* does_not_exist_s:149475394
