Will Spectre Meltdown your EPM environment? Part II

Will Spectre Meltdown your EPM environment? Part II

March 19th, 2018

Since our last Meltdown post, Intel have released stable firmware for our server CPUs. This means we have now been able to run our tests with not only the Microsoft patches in place but with full Spectre/Meltdown mitigation at CPU and OS level.

We have now also added Hyperion Essbase to our Spectre/Meltdown Tests.

The results from the testing we did in February with just the Windows Spectre/Meltdown patching showed a 3 to 5% reduction in the performance of Hyperion Financial Management (HFM) tasks.

Now on physical servers, with both the Intel firmware and Microsoft patching present, we have rerun all our tests. The results are worse than we feared and we are seeing a 4 to 5% overall slowdown in HFM performance for a variety of tasks. For a variety of short and long running Essbase calculations we are seeing a slowdown in calculation time of between 3 and 7% with an average of 4%.

As it turns out, the Intel CPU firmware patch has had little impact on calculation performance, with the biggest effects coming from the installation of the Microsoft Spectre/Meltdown patches themselves.

If you would like to discuss the implications of Meltdown and Spectre patching on your environments, get in contact with us at inlumi.
