Changing the ThreadRead INSERT to INSERT DELAYED (where to find it, plus opinions?)

[SDB]

Ah, good point, it would be REPLACE, of course.

Understood re threads not appearing to be read until the REPLACE happens. But in my previous experience, these things run within a few seconds anyway, so its unlikely to be a regular problem. Certainly worth the test in order to keep load a bit lower IMHO.

Any advice where I can find this query?

Cheers
