Hyper Threading on Open Servers

[CarlosDias]

Hi,

I have a cluster of HPE Proliant 360 Gen 9 and another cluster Gen 10, running Gaia 81.10 and planning to upgrade to 81.20

This clusters are apparently working with no problem with Hyperthreading enabled, but recently I found  SK108200

I have all the other BIOS settings as required, except that I have HT enabled.

Is is still not supported on recent Gaia releases?

I found no problem at the moment, but am a bit concerned with this SK, and ig I should disable HT

Can someone advice?

Regards

I would suggest to ask CP TAC - they should be able to answer your question!

I would disable hyperthreading regardless of whether it's supported or not. For firewalls, the perceived overall performance of the system is most strongly correlated with the performance of a single thread. With hyperthreading enabled, each real core can do maybe 25% more work in a separate thread, but the second thread generates more heat, which limits how much the processor can overclock itself for single-thread performance.
