Blocking Profiling

Testing and Tracing allows us to see blocking profiles.

Running a Test Based Blocking Profile

We can get blocking profiles by running a test.

Generate a block profile from running the test.

$ go test -blockprofile block.out

Run the pprof tool to view the blocking profile.

$ go tool pprof block.out

Review the TestLatency function.

$ list TestLatency

Running a Trace

Once you have a test established you can use the -trace trace.out option with the go test tool.

Generate a trace from running the test.

$ go test -trace trace.out

Run the trace tool to review the trace.

$ go tool trace trace.out
