go get github.com/lorenzb/goprofile

Usage: goprofile [-o output binary] [-p profile] [source files... | package]

Rule of thumb: 'go build' + profiling instrumentation = goprofile.

goprofile compiles the given files/package into an instrumented binary.
The instrumented binary is like the vanilla binary created by 'go build' but
outputs profiling information.

If no source files or package are specified, goprofile will attempt to treat
the current directory as a package.

Flags:
  -buildflags string
      arguments to pass on to the underlying invocation of 'go build'
  -h
  -help
      show help
  -inplace
      perform instrumentation in-place
      DANGER: This will overwrite your source files!
      Only use this if your files are under version control.
  -o string
      path to instrumented output binary
  -p string
      path to profiling output
  -v
  -verbose
      print verbose output
  -work
      print the name of the temporary work directory

Examples:
1)
You have written a simple exploratory program that resides in the file
"myprogram.go" in the current working directory. To profile it, you run
    goprofile myprogram.go && ./myprogram.profile && go tool pprof myprogram.profile myprogram.pprof

2)
You have a complex application that you want to profile on a remote server.
You want the profiling output to be written into your home directory on the
server. You run
    goprofile -p ~/trace.pprof module/path/of/your/complexapp
    # copy file complexapp.profile to the server
    # on the server, execute your complexapp.profile binary
    # copy the ~/trace.pprof from your server to your local machine
    go tool pprof complexapp.profile trace.pprof

Details:
If goprofile receives multiple source files as arguments
(e.g. goprofile foo.go cmd.go), it will name the output after the first file
(e.g. foo.profile). If a package is passed, the output will be named after the
last element of the package path. If nothing is passed, goprofile will name
the output after the current working directory.
