I figured as much for atime, thanks Otis! I haven't ran benchmarks just yet, but I'll be sure to share whatever I find. I plan to try ext4 vs xfs.
I am also curious what effect disabling journaling (ext2) would have, relying on SolrCloud to manage 'consistency' over many instances vs FS journaling. Anyone have opinions there? If I test I'll share the results.
