Three machines - an X32 x86_64 (AMD Opteron 6272 @2100 MHz) at rack #1/slot #1, - an X4x2 x86_64 (Intel i7-2600K @3400 MHz) at rack #4/slot #6, and - an X4 ARM (i.MX6 Quad @996 MHz) at rack #8/slot #7 are running a v3-patched 3.12.15-rt25 kernel now. I'll equip more machines later.
What I can say so far is: - No evidence for any regression, no crashes - Performance certainly at least as good as unpatched, probably better
I'll do more tests and come back with more precise performance comparison data.
Thanks, -Carsten.
