I agree with @jmorris, awesome blog post!
It’s particularly interesting how much more effect it had on memory utilization than disk. Was this a memcached or persisted bucket?
If persisted, another factor to watch for on disk utilization might be letting the server idle for a while. I seem to recall hearing in a session at Couchbase Connect last year that the built-in disk compression is delayed until the server runs some maintenance in the background. Don’t hold me to that, though.
Thanks,
