Hi,
I am getting 100% CPU usage from tracking script on 3.9.1 with PHP 7.3. I have tried to disable tracking in config but CPU is still 100% (after webserver restart).
I have tried to run Blackfire on tracking script and it shows that 38% of time is spent on INI files parsing.
It seems pointless to parse the files on every request. Is it a bug or is it by design that there is no cache?
