> The recommendations on http://cassandra.apache.org/doc/latest/operating/hardware.html are pretty out of date.  We should improve the following:
> * GC recommendations.  We (The Last Pickle) routinely use 16GB heaps with 8-10GB of new gen, Survivor ratio of 4-6 and max tenuring threshold of 6.  It works far better than G1GC
> * The instance sizes in AWS are pretty outdated.  M1s are years out of date.  i3's work well with NVMe disks, EBS works OK if you want easy backups and replacements.
