Memory Based Planner performance after Spectre/Meltdown mitigation patch
Has anyone encountered performance issues in the MBP after applying the spectre/meltdown firmware patches? I've tried searching the forums, support, bugs/patches and i don't get any obvious hits.
The firmware patch itself states that it could cause an impact of 10 to 15% under certain conditions, however I've seen the Planner double in runtime since the spectre/meltown mitigation patch was installed.
We're on version 12.1.3.9.1, with the concurrent manager/app tier running on a SUN T4 supercluster node (i think...sorry i'm more ASCP than hardware).
EDD plan, Constrained (Classic)
thanks!
