RAM shouldn't be a problem. I have a box with 144GB RAM, running 12 instances with 4GB Java heap each. There are 9 instances wrting to 1TB of SSD disk space. Other 3 are writing to SATA drives, and have autosoftcommit disabled.

I mean 15s on SSD drives is a long time to handle a 4GB index. How much RAM do you have and what size is your max java heap? https://wiki.apache.org/solr/SolrPerformanceProblems#RAM Thanks, Shawn
