# Profiling is a descriptive look into the way the server operated

# log, as this creates a proscriptive specification about how the
31
# server should work in the future -- or it forces everyone who
32
# changes the server significantly to record the test results again,
33
# and that violates the spirit of our tests. Please don't include
34
# execution-specific data here, as in all of the "show profile" and
35
# information_schema.profiling results.
