hi,

Is anybody using production FreeBSD systems with 1-2 TiB+ RAM?
This is larger than most FreeBSD systems I've dealt with personally.

I'm interested in any aspects of tuning & performance you might have
encountered.

Workload is PostgreSQL on ZFS, possibly with co-located applications.

If you have info that can't be shared publically, feel free to 
contact me directly.

A+
Dave
