Things are running slowly, and one reason might be that the code is using JSON::PP and not JSON::XS?

When I do Data::Dumper on some data, I’m seeing ‘JSON::PP::Boolean’ for the true/false values. Is that confirmation that the code uses PP or might that be a red herring?

There is a dir for x86-linux-thread-multi/auto/JSON/XS with XS.so inside it. Does that tell us anything definitive?

I thought that ‘use JSON’ would detect the availability of the XS module and use it if possible, is that correct?

TIA
