Helped fix site performance problems
by scmsteve·1 week ago
I originally found this becuase I was trying to monitor memory usage to help diagnose poor site performance. It works well for that. However, it also has a tab with a lot of other statistics and it was some of these that helped me track down some opcache issues. Site load times went from TTFB of about 2.25s to 0.6s after tuning! I am very thankful for this plugin, you should give it a try if you are trying to get some very useful stats. The inclusion of an AI prompt is also very nice as it might help you figure out what the numbers are telling you.
Displays the memory limit & current memory usage

Minimal, clear and useful. This plugin helped me to monitor the memory size on comfortable way. A little but nice debug tool.

Great little plugin.
Sloppy

Plugin is reporting 2MB php memory when all other tools, including my host, reports 2GB. This typo is preventing me from getting some other plugin support.
