comment Read performance of old LTO-2 tape
As per the detail I put in the question, the time is consumed by the device-side IO latency of each read. Note the iostat output shows a high %b but zero %w.

They were written with a gzip stream piped into dd bs=10240 of=/dev/rmt/1lbn

Unfortunately this doesn't help. I actually tried using mbuffer by Thomas Maier-Komor for similar reasons. However, the bottleneck appears to be somewhere else.

How could this be faster than dd to /dev/null?

comment Having public IP addresses for computers in private network
Updated to say "built-in security of a private address". I agree that NAT itself doesn't provide security. The point I was making is that a public address is accessible from the internet unless it is blocked (e.g. a firewall), whereas a private address is not accessible from the internet unless you specifically make it accessible (e.g. permissive NAT or port forwarding).

revised Having public IP addresses for computers in private network
Removed "built-in security of NAT" because NAT itself doesn't provide the security
