Thanks to the recent kernel proflling implementation, 4lDO2 discovered that a huge bottleneck in the context switching code, was simply reading the system time. That involves reading hardware registers from the HPET, which although reasonably fast on real hardware, is particularly slow on VMs as it requires expensive VM exits. This cost is now avoided by using the [TSC](https://en.wikipedia.org/wiki/Time_Stamp_Counter) using [KVM's](https://en.wikipedia.org/wiki/Kernel-based_Virtual_Machine) paravirtualized system time API, resulting in a massive speedup.
This improvement is unfortunately not applicable for Redox running on real hardware. However, most recent CPUs support an *invariant TSC*, in which case the logic would be very similar to the paravirtualized logic, after the frequency has been determined at boot time by calibration. This will be implemented in the future, but for now, the real HPET is reasonably fast.
