Did this type of behavior occur under freenx? Just don't recall this type of reduced speed while suspending a session on the client side and running something overnight.  I've recently installed a Windows update on the client side and updated our ubuntu 18.04 LTS server with mate DE. Any input would be appreciated. Thanks.

I cannot give you a percentage. It depends on the workload. There are
two locations where the nxagent will sleep before going on:  The first
is where the nxagent waits for input by his clients or the real X
server and the second one is when clients are sending pixmaps to the
nxagent. Here the sleep depends on the size of the pixmap. Bigger
pixmap, longer sleep.

So sessions with a higher percentage of pixmap operations are slower
than others.

This behaviour was added in June 2016 between 3.5.0.28 and 3.5.0.29
(commit 6051dec4a1ae6decd9123a3310098baf43f45c49). So if it was active
with freenx depends on what version of nx-libs your were using with
freenx.
