As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Software-based clocksources could fix those issues and provide accurate monotonically-increasing time.

The Tick-Tock release cycle basically fell apart by about 2015 , as Intel was unable to move from a 14nm manufacturing process to a 10nm manufacturing process. Older Intel processors are more vulnerable to these exploits, and they suffer more of a performance decrease from existing software and firmware-level fixes.
