multiple indices

dear solrs - thanks for all your help.
   
  I have multiple applications (blogs/forums/video/etc) - each of these is independent (no need to perform queries on multiple indices).
  Would it be best to use multiple instances of SOLR/JVM - one for each index or use a solution where only one JVM instance is running (maybe solr-215?)?
   
  Considering mostly performance and load on the servers.
