I'm not sure this is worth complicating the code, but I did an experiment where I turned some unchanging parameters of costas loop and turned them into template parameters.
With other minor "caching of function calls" it seems to speed up by about 5%. Nothing like https://github.com/gnuradio/gnuradio/pull/3076. What's the best way to benchmark this for some A/B testing? I could share my ugly code that gave me ~5%, but if there's something better I'd rather use that. I'm mostly posting this in the spirit of publishing negative results.
