PS Either it is me or suricata running on the server now takes much more cpu time (twice more it seems) on Ironlake than previously with kernel 3.14.79...

This "being busy all the time" seems like an excuse for me to do (less important) things poorly, so maybe I should do something about that. Like not checking Phoronix during the day while I'm supposed to be doing something else...

Hey Michael you might want to do some testing with wine, one of the patches which I think is related to KPTI mentions Wine specifically.

x86/pti: Put the LDT in its own PGD if PTI is on
(snip)
This will significantly slow down LDT users, but that shouldn't matter for
important workloads -- the LDT is only used by DOSEMU(2), Wine, and very
old libc implementations.

Congrats Michael your benchmarks are being featured all over, just seen your benchmarks in a Spanish tech channel.
They guy on youtube said that this would take like 10 years to solve in a hardware level? is that correct? if that's the case you can't blame Intel that much because there's not much they could actually have done by delaying their last gen processors.
