Excessive disk usage
I added columns for reading and writing from the disk to htop and was surprised, their value for xfce4-panel is very large(3,6 GB read, 1,4 GB write), this is only 9 hours of uptime, and 6-8 hours of this time fell on the night, when I was asleep and the computer was completely idle
$ xfce4-panel --version
xfce4-panel 4.16.3 (Xfce 4.16)
$ uname -a
Linux home 5.12.6-arch1-1 #1 SMP PREEMPT Sun, 23 May 2021 00:45:50 +0000 x86_64 GNU/Linux
