My desktop is a Supermicro X7DAE dual quad core Xeon (2Ghz), with a

History:
Ubuntu Studio (using "Studio) afterwards) 16 ran fine; v 18 was
extremely slow once installed, taking many minutes to complete simple
tasks. I ran 19.04 but although faster than 18 it was still much
slower than 16.
I have since switched to XUBUNTU 19 on the same hardware, speed is OK.
I do not know the Xeons well. I do know that much of the RT patches
that have been added to main line kernel were developed on the Xeon as
well as i3-7 processors. And the lowlatency kernel is only slightly
different from generic. Still, I would at least try running the
generic kernel. Note that the way GRUB works in Studio is the latest
lowlatency kernel is listed first followed by the latest kernel (which
may be the same lowlatency kernel above it) the only way to ensure the
generic kernel is selected is to use the third option which gives a
sub menu of all the kernels to choose from. This is a packaging oddity
but does insure the lowlatency kernel is default.

Thank you for your response. I'll try your suggestions.
