[ubuntu-studio-users] 20.04 solves my problems with older Xeon CPUs and v18 and 19

[Mike Squires]

The low-latency kernel in Studio versions 18 and 19 caused my system to 
slow down dramatically; I solved this by installing a standard kernel 
version so I could continue to use the environment.  The slowdown seemed 
to be due to my use of a 3ware RAID controller (very slow reads/writes, 
normal performance once in memory).

This problem does not exist with 20.04.  I ran the old UnixBench 
benchmark and the scores are nearly the same as those I clocked with the 
standard kernel on v19.

Hardware is a Supermicro X7DAE, dual quad core Xeon E5335, 3ware 9750 
RAID controller, 2 Seagate SATA 2 TB drives in RAID 1 array, AMD HD 5500 
video.  Sound is an older M-Audio PCI card (Delta 66).

Thank you very much!
