Well, analyze if you need to create an excessive overhead into the MySQL Server because a simple INSERT. What you must have a look is it:
- How much data this connection is delivering to MySQL's handlers? - A word DELAYED in this case is making MySQL surfer? Perhaps, you are sophisticating something that do not need it. Besides it, analyzing your "log table", I imagine this table can be an Archive table instead of MyISAM. Log tables or history tables can be controlled by Archive Storage Engine to have more compressed data. Although, Archive Storage Engine only supports SELECT and INSERT. Maybe, a good deal to you, get rid of you INSERT DELAYED: - ALTER TABLE <tbl_name> ENGINE = ARCHIVE; Best regards. -- WB 2010/11/29 WLGades <wlga...@gmail.com> > I'm adding a table to our site that logs all page loads.
