Hi,
today I had an strange effect. I updated the Bios (Intel Microcode Update) on an Dell R620, and after that an high IO DB-VMs shows a much higher load than before (actual pve-enterprise).
An short test with pveperf shows much lesser regex-values:
an unpatched system (also updated pve, but older kernel running) shows better (normal) values
On an second system updated last week I had the same drop at the regex-value (reconiced now), but on the testsystem the regex-values are normal (but pve-nosubscription):
I must check, if the power settings was changed during the bios update, but this don't happens on the test-system and phoronix give on both systems (test-system + live-system updated last week) the same output:
Any hints?
Udo
