lwIP.
That depends:

Only if generating the hash is faster than scanning the table, so only for
big tables.
> but more memory required (and so less lightweight on the memory).
OK, but if you need ~100 entries, the table is also big. I'd say if someone
wants many entries, a hash table is still a good idea.
Nevertheless, this would of course be an option since for 10 entries, the
table & one-entry-cache is still the best solution. Also my first optional
implementation would be the sorting list, not the hash-table. I think that
this is best for sizes between 20 and 50 with some concurrent connections.
