Here is an example:
strace -e file kate &
echo 3 > /proc/sys/vm/drop_caches
hdparm -y /dev/sda

Then click to “File” in Kate and “strace” mentions the access to icons.

The size of “/usr/share/icons/breeze” is ~15MiB. But ~10000 files is
problematic for a busy HDD, so a solution could be to have one file containing
the icons. Then to load them in advance.
