Profiling

There are many profiler options to debug performance issues. These can be enabled by supplying the following command-line option and are saved in the pprof directory:

go run . --profile=cpu

Available profilers:
cpu mem block goroutine trace thread mutex

You can export the profiler output with the following command:
go tool pprof --pdf ./OpenDiablo2 pprof/profiler.pprof > file.pdf

In game you can create a heap dump by pressing ~ and typing dumpheap. A heap.pprof is written to the pprof directory.

You may need to install Graphviz in order to convert the profiler output.
