There is no hard and fast rule. As I stated earlier:
Also new in this version is 'max-cache-entries' which allows you to limit
the cache to say, a reasonable 1 million entries. I'd love to be able to
have you specify a limit in megabytes but it is very hard to measure actual
memory usage. DJBDNS can do it but it requires too much work to do it from
c++.
The actual usage will depend on the version of compiler, cpu type, version
of 'boost' library and usage patterns.
99% of people can get away with 'max-cache-entries=1000000' and be on the
safe side.
