Well, I am starting to try and improve the performance of the slowest graphs on the site, the Index/Multi-Test graphs.
I have managed to completely eliminate the need for the temp tables I had been using, migrating to a pure associative array method. This is in the code that ensures that any tests that return no results for a given time period don’t cause PHPlot to throw a hissy fit.
There has to be a way to do it faster. I have a couple of methods I am considering, but arrays within arrays scare me just a little!
Let me know if you see any performance degradations.
