--- Comment #4 from Adam Fontenot <adam.m.fontenot+...@gmail.com> ---
I'm changing the title and moving this to reflect the generic nature of what I
take the issue to be.
Adding two "see also" links. There is an existing confirmed report that
*adding* an entry to the recently used list adds ~100 ms latency to the
application calling the KRecentDocument function. There's another confirmed
report related to the privacy issue I mentioned in a comment above: KDE adds
items to recently-used even when this is disabled in the settings.
I think *this* issue is about kactivitymanagerd using inotify on
recently-used.xbel and parsing it whenever the file is updated. This doesn't
add latency to operations like the other issue, but it can consume even more
CPU time (claiming a full core in this case) because it seems to reparse the
whole file whenever it changes.
