Ubuntu Studio 19.10 runs on my Supermicro X7DAE/Xeon E5335/3Ware 9750 SATA RAID/AMD HD 5570 system but large file copies or opening large applications like LibreOffice is very slow. I had a similar problem with 18 but not with 16.
The version of 19.10 I installed seems to only have versions of the kernel installed with the low latency option installed. I installed 5.3.1 generic and ran some comparisons.
For the Xubuntu and Ubuntu Studio systems both running generic kernels the time to copy a 415MB file and time to open a LibreOffice ODS file from choice of kernel at boot time was about the same, about 5 seconds to copy the large file and 1 min 30 seconds to open the ODS file.
The low latency kernel increased the Ubuntu Studio time to copy the file to nearly two minutes and the time to open the ODS file to more than 14 minutes.
I ran the old Byte UnixBench benchmark using all three kernels. There were no significant differences between timings between the three (file attached). This was surprising given the differences in file copy and boot/open file times.
The Xubuntu timings are from a different boot drive, a pair of 2 TB Seagate SATA drives in a RAID 1 array; the two Ubuntu Studio timigns use a pair of 1.36 TB Seagate SATA drives also in a RAID 1 array.
The short answer here is that if I can use a generic kernel then Ubuntu Studio works across all of the PCs on which I need to run it; the low latency kernel, however, makes using versions 18 and 19 too slow for my needs.
I assume that this needs to be reported to Ubuntu via their bug tracking program, and I'll do that Real Soon Now.
