I think you have some issues like a conflict with another plugin on your blog (maybe because of some hooks?).
I installed “Simple History” and run the profiler on the frontend main page and the admin dashboard page:
-Frontend: it took 0.023s to load. The on_gettext function took 0.007864s and the on_gettext_detect_plugin_error_deactivation_reason function took 0.000322s.
-Backend: it took 0.037s to load. The on_gettext function took 0.008102s and the on_gettext_detect_plugin_error_deactivation_reason function took 0.009858s.
Nothing worrisome!
However, regarding the on_gettext function, it was loaded 1,502 times within one second on the frontend, and 10,429 times within one second in the backend. That can definitely artificially increase the time returned by the profiler, but not to some crazy levels though (and it shouldn’t slow down your site).
There’s nothing to avoid that unfortunately, but you can still exclude the script where the function is located (click on “Advanced Options” and in the “File and folder exclusions” field, enter: class-plugin-logger.php).
Did you try to deactivate other plugins to see whether there could be a conflict between one of them and Simple History?
I’ve also seen issues with plugins that use Composer
Can you clarify what issues?
