How "resource-hungry" is unbound?

The thing I like about dnsmasq is that it is very light and quite 
happily functions in very resource-constrainted environments. The 
environment within which dnsmasq is currently deployed is an old (though 
versatile) router with 64mb RAM and 512mb flash memory (which is quite 
old, so I am conscious of doing excessive writing on it). Even though I 
am using this router for everything which passes through the network, I 
cannot really expand and add packages too much simply because there is 
nowhere to fit these in.
