Hi @kabaaab, is the issue specific to the fbe/pixel/tracker endpoint or are there more slow transactions outside of it?

[kabaaab]

Hi @zlik from what i can tell it's specific to the fbe/pixel/tracker

[kabaaab]

This is stil an issue in our enviroment newer patches haven't made a difference.

@kabaaab Review your request logs. Bots and crawlers are one of the main reasons for this performance issue. Adding a rule to prevent crawlers from accessing the tracking endpoint fbe/pixel should help
