--- Comment #7 from Jon R Kibler <jrk1231-lo at nym.hush.com> ---
I was asked to see if I saw any of the same issues as other bugs posted. Here
are my results:

Bug 107113 -- agree performance at cold start is MUCH slower than OO. I have
also noticed that the longer LO runs, the slower it seems to become.

Bug 106958 -- I am also having document freezes while typing. Clicking icons
does not seem to help.

Bug 106154 -- I occasionally see this behavior, but not as frequently as this
bug report. However, one place that it is consistently slow is in replacing
misspellings: You select the replacement word on the right-click menu, and it
hangs anywhere from 2 to >5 seconds before replacing the word and closing the
menu.

Bug 104802 -- I am not seeing this particular behavior, but I do see it
sometimes freeze when clicking in a new cell and start typing. Under that
circumstance, I also notice that the typing lags showing up in the formula edit
box on the tool bar, and the full text of typing never shows up until you
select a different cell then go back to that cell... but I think the formula
bar echo is probably a different issue.

Bug 103571 -- I am seeing some of this, which I describe in bug 113467 which I
also have open.

Bug 103252 -- If LO has been previously running, and you quit it, then restart,
from the time that LibreOffice appears in the menu bar and StartCenter appears
averages 6 seconds. However, if you start LO after a clean login (not switch
user) it can take over 20 seconds to appear.

Bug 87013 -- Reading this, my thought is this is not a LO bug. I have several
NAS drives, and if they are mounted but have gone to sleep, they slow ANY
application down when trying to do disk access that one would think is limited
to the internal HDD, but for some reason macOS also waits to spin up the NAS
drives before responding. This is something that got A LOT worse with Sierra.
My thought is that with LO needs some shared library that is not loaded in
memory, it hangs until all the NAS drives are spun up. That said, I have tested
my LO problem with all NAS unmounted and that does not seem to solve the
problem.

Bug 113104 -- Have not seen this issue.
