	Hi,
I'm not aware of any. You indicated in another mail in this thread that
the speed is the same for older evolution, thus it's nothing with the
3.58.0, it's something else.

>From what you described, it looks like a connection problem. The last
time I saw any such thing (which is months ago), was related to my
local network configuration, not playing well with IPv6. When I
disabled it in the system on my machine it begun to work better (some
IPv6 connections could not be made for some reason, which took time to
be discovered, which "slowed down" the connections. There exist
techniques to overcome it, but they either were not implemented or were
not working properly back in the days I faced the problem).

Maybe you see something completely different, but as a matter of a
test, try to disable IPv6 in your network settings, verify you do not
use any proxy, both in the Evolution's Edit->Preferences->Network
Preferences and in the system, then restart the machine and then see
whether it works better or not.

Otherwise install debuginfo packages for glib2, glib-networking,
gnutls, evolution-data-server (libcamel) and evolution, then grab a
backtrace of the evolution process when it does these things, which
will show what it is waiting for. It means to use the packaged version,
not the Flatpak version (there you need to install different things and
run different command). You can get the backtrace with a command like
this:

   $ gdb --batch --ex "t a a bt" --pid=`pidof evolution` &>bt.txt

Please check the bt.txt for any private information, like passwords,
email addresses, server addresses,... I usually search for "pass" at
least (quotes for clarity only), before sharing it anywhere. Not that
anybody would try to fix evolution 3.46.4, it can give a clue where to
look to make it work as before.

	Bye,
