[ubuntu-studio-devel] Ubuntu Studio 18.10 fails on Supermicro X7DAE

I reinstalled on my desktop and tried using the normal LINUX kernel 
rather than the low-latency one.

Same problem, very slow operation.  My current guess is that the problem 
may be in my use of the 3ware PCI Express SATA RAID controller since it 
appears that programs run more-or-less normally once loaded but take a 
very long time to load or to open new windows.

I will next try the most recent XUBUNTU once I get the drive-swapping 
arrangement fixed.

Hardware is a Supermicro X7DAE motherboard, dual quad core Xeon 2 GHz 
CPUs, 20GB RAM, ATI 5000 PCI-Express video.  The on-board Adaptec SATA 
Raid controller is not supported by Windows 7 which is why I'm using the 
3ware controller.

20GB RAM, all ECC and registered.

3ware 9750 4 channel SATA controller with 2 Seagate 2 TB Constellation 
drives in RAID 1.

M-Audio sound card.

Operation under 16.04 is normal, as is operation under Windows 7 X64 
(system dual-boots using "grub").

UNIXBench output in HTML format is attached.  This is for the system 
running 16, not 18.  Nothing obviously odd there.
