Try reading the basic documentation that comes with 5.2-BETA, for
example the /usr/src/UPDATING file, which tells you clearly that
performance is not expected to be good unless you disable the standard
debugging options.  Also make sure you read the 5.x Early Adopter's
Guide, available on the website.
