<pre>Each "mempool" in pulseaudio is 64 MB by default, and there's one mempool per
client. Maybe gnome-shell has multiple connections to pulseaudio? 8 connections
sounds excessive, though... Maybe the server's own mempool is visible in the
client memory mapping too, so perhaps two mempools per connection are visible
in the client memory map. 4 connections sounds still a bit much, though.
The mempools should indeed not have full "physical" impact unless they're
actually fully used.
What if you set "shm-size-bytes = 33554432" (i.e. 32 MB) in
/etc/pulse/client.conf and /etc/pulse/daemon.conf and reboot? Does the
gnome-shell memory usage go down by 256 MB?</pre>
