I played with Go a little shortly after he left. Then there was no profiler; is there now?
I use the pprof package and Google perftools .
If you use the compiler gccgoinstead of the compiler 6g, you can probably use the usual GNU tools, i.e. gprof.
gccgo
6g
gprof
I actually did not do this with gprof, but at least I know what it works for gdb.
gdb
