I concur with this. As long as index segment files are cached in OS file cache
performance is as about good as it gets. Pulling segment files into RAM inside
JVM process may actually be slower, given Lucene's existing data structures and
algorithms for reading segment file data. If you have

Hi,
This talk has some interesting details on setting up an Lucene index in RAM:

Would be great to hear your findings!

A start maybe to use a RAM disk for that. Mount is as a normal disk and
have the index files stored there. Have a read here:

This is true with Lucene as it stands. It would be much faster if there
were a specialized in-memory index such as is typically used with high
performance search engines.

Experience has shown that it is much faster to run Solr with a small
amount of memory and let the rest of the ram be used by the operating
system "disk cache". That is, the OS is very good at keeping the right
disk blocks in memory, much better than Solr.
How much RAM is in the server and how much
