Comment(by dustymugs):
Wow. That'd be a lot of data which is ideal for performance testing. I
do have CA aerial imagery and parcel datasets so I'll see about trying it
myself.
I'd really like to see what the cold cache performance for that table is
in 2.0 and -trunk using single user mode in PostgreSQL. Granted, there is
no equivalent to "echo 3 > /proc/sys/vm/drop_caches" in Windows.
Oh. Also the URLs for wget are no longer valid ;-) I see Paul's recent
blog entry coming true...
