Thanks. The only slow things I can see in those logs relate to:

  * gnome-system-monitor snap - If you don't need it then please
uninstall it. This might also be a problem with your wifi.

  * DNS failures from your network provider - Please check your network
settings or try using the Google DNS server:
https://developers.google.com/speed/public-dns

If you feel the problem is memory related (which sounds most likely)
then please record output from running 'free -h', and also 'ps auxw'
noting which output is from when it was slower.

Please also don't encrypt attachments. If you want to keep them private
then you can make the whole bug private by changing its visibility at
the top right corner of this page.

Title:
  Unlocking the screen is slower the older the session

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  Unlocking the screen takes several seconds after a session is a day old. 
Initially it is fast.
  Closing all programs and locking/login doesn't help.
  Logout/login DOES help.
  It feels as if the time is related to the maximum RAM used.

  Output of journalctl -b around the time of login:
