Memcached is for scalability not speed, fetching the prefs from
memcached is actually slower than fetching them mysql, unless your
database is under severe load. (We benchmarked them). If you run Koha
under plack (which you can do with a bit of set up from 3.8.x on), the
preferences are cached in persistent variables, there is obviously a
huge improvement with that.
