# Tests for PERFORMANCE_SCHEMA

--source include/not_embedded.inc
--source include/have_perfschema.inc

#
# Important note:
# this test is extremely sensitive to how threads are running inside the server,
# so it has it's own -master.opt file, to enforce it runs alone in mysqld
#

# Setup

flush status;
flush tables;

# Remove to debug
--disable_result_log

# Make sure the internal server caches are all full
