Unmaintained Slow query logger 1.3.0

No permission to download
Compatible XF 1.x versions
Additional requirements
php 5.6+
MIT Licence
Visible branding
Generates an error log entry when a slow query is detected. No configuration required.

Once it has been running and reporting issues, I recommend disabling the add-on until you have pushed out fixes or understood why the previous logged queries are occurring.

It is not recommended to leave this add-on enabled.

The initial start of a search is known to take a while, this appears to be a design issue where all content needs to be loaded and then verified.

  • Works on a single query at a time, not all queries for a request.
  • Only logs slow public queries.
  • Under "Performance", Slow Query Threshold is in seconds and allowing 0.25 second steps.


I recommend using Add-on install & upgrade to install this add-on.

This addon will show you problems that you never knew existed. If not for the Slow Query Logger: my members would still suffer 6 second load pages on some page, because some of the addons installed had problematic code or could use improvements. I can recommend this addon to any webmaster who takes performance seriously.
Much needed when a certain something needs to be checked and removed.

Helped us in multiple cases to figure out what was causing slow query to come up.
