I often get some unpleasant latency when editing org-mode

It is not namely typing latency, but I have noticed lags while moving
over collapsed headings with "up" key (with "down" it is not so
apparent) e.g. in overview view. It has happened after linux upgrade,
emacs version changed from 25.2 to 25.3, system package with org mode
updated as well. The org file has significant size: 50k lines, 2Mb. I
have created a LXC container to compare performance with older emacs. It
is quite strange. With org version from git, emacs version is not really
important, flyspell mode is irrelevant.
It seems, it depends on loading order. From earlier experiments the
following line survived in my init.el just below of custom-set-variables:
(require 'org-protocol)
as soon as I commented it out (independently if it is added to
org-modules), moving over headers has become significantly more
responsive. A side effect: with that line, "#+STARTUP: overview" was not
necessary. Sorry, I do not have any numbers from profiler.
On the other hand, removing of that line does not have so great effect
on org mode 9.3.1 from the system elpa-org package. Latency is still
noticeable.
