…This means you'll only add more website instances when usage demands it, not because you have a SQL query that doesn't perform well under high load.
The Cool Stuff to Ask Us About

I read the logging code in MySQL 5.6.10 source, in file sql/ log.cc. I discovered that they have refactored the way they write to file-based logs versus table-based logs, but one particular feature I was looking for has not changed.
When writing slow query information to the log file, it outputs the query time and lock time as floating-point numerics to microsecond scale:

But back to what the above strace shows. In MySQL 5.5 you can find in sql/ datadict.cc a function named dd_frm_type(). In MySQL 5.1, for some reason yet unknown to humans, it lives in sql/sql_view.cc as mysql_frm_type(). What this code snippet does is:
open the FRM
read 10 bytes ("header")
