Good point. :-)
I intend to deploy this system as a database server running Postgresql
8.1. The database is huge (30-40Gb) and can easily grow (it has gone as
high as 100Gb). I expect as many as 1000 concurrent database connections
now, and a potential need for scaling this up later.
I'm aware of the SystemV memory tuning issues related to running
Postgres on FreeBSD and I'll address those as soon as I can get the
system to see the RAM.
I tried just installing the stock PAE kernel, but the system still
doesn't even acknowledge the RAM above 4Gb. Is this because I have not
yet performed the tuning?
Thanks for your help!
