thunderbird operations are very slow
i recently upgraded to ubuntu 18.04 from ubuntu 14.04 and to the latest versions of thunderbird & firefox. ever since the upgrade, all thunderbird operations take a long time to perform. it can take 10-20 seconds to over a minute. moving an email from the inbox to another folder, marking as read, downloading greaphics in an email & other ops are affect. at times, my system cpus are pegged at 100%, which prevents my system from being used until thunderbird finishes what it is doing. sometimes it takes 60 seconds or longer to close thunderbird.
what happened? it used to be a very fast & responsive program. now it acts like an arthritic slug.
thanks Mike

ISP/MSP are integrating new features like OAuth2 into their server systems, allotting more resources, etc etc, so now many things are queued & not-instant, thus slow, etc.
but you cpu uasge should not jump to 100%, something else is going on.
use "nice" or derivative tools to assign lesser processing & priority for the "thunderbird" process.
in macOS (darwin unix* based) i do this: obtain thunderbird's process id with "Activity Monitor", then in "Terminal": /usr/bin/renice -n 20 -p TB-pid#
that allows other apps to get fair priority.
and begin to investigate what exactly causing this conflict or cpu usage.
i suspect something else is also scanning (or creating hash/checksum, etc) files, etc. and remove unavailable DNS entries , disable unused mail-account, etc.
