Comment:

 Hi there, thanks for the ticket.

 I'm sorry to hear you are having issues with your websites since the
 latest update. Unfortunately, it it doesn't look like there are any
 actionable items for WordPress core here, as Google PageSpeed results
 depend on many various factors.

 Replying to [comment:2 123nadav]:
 > But is very important to me, and like i said i know 99.9% the issue is
 from the core.

 Here's the
 [https://core.trac.wordpress.org/query?status=closed&group=resolution&milestone=5.5.1
 full list of changes in 5.5.1]. If you can identify a performance issue
 with a specific change, please feel free to comment and provide some more
 information, so that the issue could be investigated further.

 Until the issue is identified, confirmed, and can be reproduced with some
 steps on a clean install in more than one environment, this topic is best
 discussed on [https://wordpress.org/support/forums/ support forums].
