19.04 install went well but extracting my home directory, a 421 gb file, was taking many hours. "iostat" indicated 2mb/sec rate. I tried booting 16.04 and running from the install disk; this completed in two hours.
Only other problem has been a slowdown in a VirtualBox Windows 7 x64 image. I traced part of the problem to the HP 8710 driver which behaved normally under 16.04 (with an obsolete version of VirtualBox, v5) but was not happy with VirtualBox 6.06 which is current.
Only other problem was "unixbench"; the version from "Software" ran properly under 16.04 but the version currently available, which appears to be the same, crashed with an "illegal instruction" error. Downloading the source and compiling it created a version that ran correctly. Text and HTML output is attached.
Hardware is a Supermicro X7DAE dual Xeon 5300 quad core motherboard (have 2 5472 CPUs on order) using a 3ware 9750 SATA/RAID controller. Video is an ATI/AMD 5000 series PCI-E card; sound is via an M-Audio card which is correctly controlled by "envy64control".
I am now set up for a quick swap of boot devices (RAID 1 off the 3ware card) so will be happy to test versions as they come out.
In case anyone is curious - I ran a Tandy 16B at work, and another at home starting in 1986, using Radio Shack XENIX/68, a UNIX v7 port by Microsoft for the Apple Lisa licensed to Tandy. Thanks to the backup tools and cross-system portability of the UNIX variants my home file system has never been lost through disk failures and contains files with creation dates back in the 1980's. I ran SCO variants for a while, and in 1990 started using 386BSD and FreeBSD which I still use on my back-end servers.
