Profiling the D code with gperftools (Google Performance Tools)
March 30
Hi,

I have been working on a Bioinformatics tool that handles large matrices, say 8000 rows * 8000 columns.

I was interested in profiling my D code and find out which function executes for what duration(clock ticks). I used gperftools(Google Performance Tools) and hence,
created the D bindings for it and released it as a dub package "gperftools_d"

Links:
1. https://github.com/prasunanand/gperftools_d
2. https://code.dlang.org/packages/gperftools_d

It shows really cool output as graph visualizations and which are the critical nodes (functions that take maximum time).

A very simple example of visualization can be found [here](https://github.com/prasunanand/gperftools_d/blob/master/examples/profile.pdf).
Here I am calculating Fibonacci series.

It has other cool features too like heap_profiling, stacktrace, etc.

I hope this tool would be helpful to D community and would love to hear your feedback.

Regards,
Prasun

Nice.

Perhaps you could try and get D functionname demangling in gperftools?  ;-)

cheers,

Thanks :)

Function-name demangling might be there in the next release :).
