"and I ran BIND on the kind of potato that has a quarter of the RAM that a raspberry pi has"
256MB RAM? - bloody luxury!
A very quick and a bit rubbish experiment:
$ ping 9.9.9.9
5 packets transmitted, 5 received, 0% packet loss, time 10ms
rtt min/avg/max/mdev = 9.982/10.838/12.531/0.888 ms
$ dig @9.9.9.9 www.google.com A
;; Query time: 13 msec
DNS is pretty quick. Note how I mistakenly use ICMP and a UDP service response time to imply something. If I'd tried to claim that DNS adds about 5ms overhead, I would have been first to put the boot in. The basic result stands though - DNS is quick. The above results are from: my laptop -> wifi -> switch -> switch -> APU2c based pfSense box with quite a lot going on -> modem (FTTC in UK - PPPoE/A) -> ISP .... etc.
only the first revision (and the A/A+ until the 3A+ came out) had 256Mb. It was soon upgraded to 512 as one of the first design changes (before moving to the "plus" form factor with 40 pin GPIO header) the early A's even had 128Mb but they are a rare thing as the original A was not promoted much before the first upgrade cycle.
