This is interesting, I was running F33 with the the following
configurations.

BTRFS RAID1 with two subvolumes / and home

The laptop has 32GB of RAM and 4GB ZRAM

I was experiencing delayed reads especially when I am trying to open a
file from any application (gedit, TeXstudio, etc.) for example, when I
click file open, I will have to wait over 30 seconds before nautilus
opens so that I can select the file. 

To see if it was related with filesystem I switch to my traditional
installation with RAID1, LVM and XFS filesystem and I haven't
experience the similar behaviour when I was using BTRFS. I will try
your recommendations and see if it resolves the issue.
