Intel CPU Security Mitigation Costs From Haswell Through Panther Lake

Written by Michael Larabel in Processors on 12 March 2026 at 11:50 AM EDT. Page 8 of 8. 16 Comments.

The OpenJDK Java performance impact hasn't been impacted much by running without mitigations in a few CPU generations.

Importantly was also no CPU power consumption difference observed across the range of tests with the Core Ultra X7 358H Panther Lake model used for this benchmarking.

While some Linux users swear by running their system(s) in "mitigations=off" mode for better performance, there is little benefit in doing so for Core Ultra Series 3 "Panther Lake" or other recent Intel CPU generations for that matter. Only if going back several generations is there anything really to gain from running with CPU security mitigations disabled for better Linux performance.
