Hi Chak Rather than comparing the overall size of your index to the RAM available for the OS disk cache, you might want to look at particular files. For example if you allow phrase queries, than the size of the *prx files is relevant, if you don't, you can look at the size of your *frq files. You also might want to take a look at the free memory when you start up Solr and then watch as it fills up as you get more queries (or send cache-warming queries).
