I advise you to have 7GB RAM better (more would be better if you have a lot
of data per node). But the real difference is made when you use SSDs or
RAIDs of SSDs, since the bottleneck is the disk throughput in most cases.

You still have the same amount of RAM, so you cache the same amount of
data. I don't think you gain much here. On the other side, maintenance
procedures (compaction, repair) may hit your 2CPU box. I wouldn't do it.
Thank you,

Quick question about systems architecture.
Would it be better to run 5 nodes with 7GB RAM and 4CPU's or 10 nodes with
3.5GB RAM and 2CPUS?
I'm currently running the former, but am considering the latter. My goal would
be to improve overall performance by spreading the IO across more disks. My
