You cannot be sure of that. It is not mandatory, but the system should
share memory mapped files with the disk cache.

Shalin,
There's one point to test without caches, which is to establish how much value
a cache actually provides.
For me, this primarily means providing a benchmark by which to decide when to
stop obsessing over caches.
But yes, for load testing I definitely agree :)

Yeah, I was talking about load testing. Tuning caches by looking at
evictions and hit ratio is what's useful.

There are no disk caches as such. There is no point in testing without
caches. Also, Lucene has field caches required for sorting which
cannot be turned off.

Restarting Solr won't clear the disk cache. When I'm doing perf testing, I'll
sometimes run this on the server before each test to clear out the disk cache:
echo 1 /proc/sys/vm/drop_caches
