55773 files in ~/.cache/fontconfig/
It looks weird. Some of the files are 6 years old. I'm not sure if this cache is effective at all, as most of large caches I have seen use prefixing to speedup filesystem lookup.
root@localhost:~# echo 3 > /proc/sys/vm/drop_caches
root@localhost:~# time ls -l /home/bodqhrohro/.cache/fontconfig/ > /dev/null
real 0m25,959s
user 0m0,964s
sys 0m2,015s
Moreover, it's still there after I ran fc-cache -frs
(from user, of course), with the same timestamps. Would it be safe if I just clear the directory? Or all of these thousands of files will reappear anyway on the next cache rebuild?
