I have been reading about the profiling here it is explained using net_http_pprof and here runtime_pprof. So, what are difference between these two and which one should be prefer over another. And please don't paste the overview definition from the given links
net/http/pprof exposes the pprof profiler data via a web interface. If you're writing a server-based system, this may be useful since you may not have access to the host.
runtime/pprof will write the profiler data to a data file that you can then convert into various image or document types. If you're writing a system that can't or won't have a web interface, this is probably the one to use. Either way they expose the same data.
