A very interesting read! Thanks for looking in to this.
So basically with a few "simple" fixes you cut memory by 25%. That is a nice
result. From the top of my head, the simple tests I did with BIND resulted
in another 25% drop of the memory used, so we are half way there :-)
As you say, checking the temporary allocations in ldns seems to be a worth
while endevour, and I'm willing to help (if needed).
About the rdf structure in ldns. Yes, I see that from a memory allocation they
suck, but at the time they made ldns tick. I.e. when we introduced the rdf
type in ldns all the RR types became very easy to implement.
Having said that, I think a higher memory usage compared to BIND is justified,
as ldns is a generic (extensible) dns library.
Are there any "next steps" planned?
