How can I configure the system so that patches for Specter and Meltdown do not effect the performance. If adding the following kernel parameters help:
pti = off, nospec, spectre_v2=off
Actually one of my customer runs SAP ERP atop SLE servers. SAP ERP is a trusted application and only local and trusted users access the system. Customer is asking me to configure the system so that performance impact could be avoided.

Please help
