Note that the StartCPUProfile call takes an io.Writer. Therefore a simple *bytes.Buffer suffices. No files need be created. You can be much faster than the file system. > func StartCPUProfile(w io.Writer) error Writing a benchmark for your subsystem is the hardest mentally, but most likely the best choice for the long term.
