One of the issues holding back performance of the API is the problem of hashing.
Whilst banning BASIC authentication with passwords will help, the API Token scheme
still requires a PBKDF2 hash - which means that heavy API use (using Tokens) can
still cause enormous numbers of hash computations.
A slight solution to this whilst we consider moving to using JWT based tokens and/or
a session orientated solution is to simply cache the successful tokens. This has some
security issues but this should be balanced by the security issues of load from
hashing.
