Added: on 18th June, 2019
I found an article about a workaround, Controlling the Performance Impact of Microcode and Security Patches for CVE-2017-5754 CVE-2017-5715 and CVE-2017-5753 using Red Hat Enterprise Linux Tunables. I tested it on CentOS7.6 (CentOS7.6WA in the chart) and confirmed the improved performance. It also worked well for RHEL8 (RHEL8WA in the chart).
