Increase ramBufferSizeMB from 32 to 100

This makes Solr use more memory and increases performance. Details at
available at https://issues.apache.org/jira/browse/SOLR-4074. I considered
setting it to 320, which is what I did somewhere else, but apparently
there are deminishing returns when using values over 100.
