IDF port advice? about diy-alexa HOT 2 CLOSED

Could be one of two things.

The most likely will be the build flags that are being used. In my code I used the -Ofast flag which compiles with all the optimisations turned on and also has slightly less accurate maths - see here for the different options - https://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Optimize-Options.html

You may be building in debug mode or with less aggressive optimisations - it's most likely that you are building in debug mode as I think that might be the default (though I'm not sure).

The other possibility is the core you are running on - I think I pinned the recognition task to one of the CPU cores so that it didn't run on the same core as the WiFi and the audio sampling - but I don't think it made a dramatic difference.

Unfortunately, so far, the build flags have made little difference (nor pining the task/raising priority) - though I had actually set it compile for size optimisation and forgot...

No doubt I'm missing something somewhere else too; I'll have a better read over the build flags tomorrow.

Much appreciate the help (I'll close the issue :)).
