           <li>Added a <a href="https://man.openbsd.org/ktrace">ktrace(1)</a> -T option to make time-related system calls more prominent.
           <li>Added tsc_delay(), a <a href="https://man.openbsd.org/delay">delay(9)</a> implementation based on the TSC, to amd64.
           <li>Used an LFENCE instruction everywhere RDTSC is used for a time measurement, reducing the jitter in TSC skew measurements.
           <li>Introduced <a href="https://man.openbsd.org/gettime">gettime(9)</a> and <a href="https://man.openbsd.org/getuptime">getuptime(9)</a> and substituted these for time_second(9) and time_uptime(9) throughout the kernel to prevent split-read problems on 32-bit platforms.

           <li>Improved CPU frequency scaling in automatic performance mode by removing accounting for offline CPUs.
