SUMMARY

STEPS TO REPRODUCE
1. have a bit of files (6.5k in my case) with a lot of tags (I'd say that the average file has ~30 tags)
2. open dolphin
3. dolphin hangs (first render is done, but then it doesn't respond for quite a long time (few minutes), after which it starts responding normally). This sometimes happens again even without closing dolphin and just switching back

OBSERVED RESULT
Dolphin hangs

EXPECTED RESULT
Dolphin works normally (even if the tags took quite a while to load in the background, but using getfattr for all the files takes between 600ms (cold run) and 100ms (after cache)).
