The administration menu works quite laggy. The browser receives the request in about 0.5 sec on my local machine which is about 20x slower that other requests. It generates about 3 sec. lag when connecting to the remote instance.
The culprit is load_administration_settings function inside /lib/navigationlib.php
the first run of the code launch code in the condition starting here:
xls file attached to the ticket shows particular times of invocation of the function load_administration_settings during ajax request.
The first run of this function takes about 95 % of execution of whole ajax script
Is there a way to optimise the functioning of the menu, maybe implementing a cache could do the job?
Thank you for considering my request.
