kib 13a9f42818 Use struct vdso_timehands data to implement fast gettimeofday(2) and ... clock_gettime(2) functions if supported. The speedup seen in microbenchmarks is in range 4x-7x depending on the hardware. Only amd64 and i386 architectures are supported. Libc uses rdtsc and kernel data to calculate current time, if enabled by kernel. Hopefully, this code is going to migrate into vdso in some future.
