+as @url{http://www.brendangregg.com/offcpuanalysis.html, Off-CPU} (e.g. I/O)
+time together.
+
+Go's builtin sampling CPU profiler can only show On-CPU time, but it's better
+than fgprof at that.  Go also includes tracing profilers that can analyze I/O,
+but they can't be combined with the CPU profiler.
+
+fgprof is designed for analyzing applications with mixed I/O and CPU
+workloads.  This kind of profiling is also known as wall-clock profiling.")
