Hi,

Has anybody seen any information from IBM in relation to Spectre & Meltdown
patching for Spectrum Protect servers?
We have a customer who has found that systems that do lot's of small IO's
that performance can drop 50% on intel systems, these were seen with
synthetic benchmarks, not actual load.

So this was certainly not a Spectrum Protect load but I was thinking that
Spectrum Protect might fall into the category that can experience some sort
of performance drop when patched for Spectre and Meltdown.

Does anybody know what is the impact of these patches on Spectrum Protect
systems?

Will the blueprints need to be adjusted for instance or is there some
percentage of lower performance we should expect after patching and does it
vary per platform?

Regards,
   Stefan
