Free version is indeed useless
by ypro·1 week ago
Only the pro version has detailed profiling per PHP script file, so this functionality exists, but you can’t be bothered to at least show the correct per plugin timings in the free version – but instead say “well, some of your plugins use composer, so this means nothing, good luck“.
Very nice plugin and coded well!

Thanks for your work!
Waste of time – free version is useless
by jen000·5 months ago·1 reply
The graph which actually shows the info that you need is only available on the Pro version. Waste of time.
Unreliable Data
by eugenend·10 months ago
Useless – presents unreliable data which leads to false positives, huge problem with measuring plugins using composer, gives completely wrong impression of what is really going on – total waste of time.
Sehr gute Visualisierung von Ladezeiten von Plugins und Themes
by lacoste89·10 months ago
Genau so ein Plugin habe ich schon lange gesucht. Damit erhält man eine sehr gute Übersicht, welche Plugins und Themes die Ladezeit einer Webseite auf einer bestimmten Seite verzögern.
