So what parameter can be added to bitcoin.conf to receive incoming faster connection more quickly, assuming the one who asked question didn't add line which makes it worse than default configuration?
It would depend on what the bitcoin.conf contains. Asking to see the bitcoin.conf was logical because configuration errors would be spotted.
For the other question, I suggested using a search engine from a link but after it was removed I suggested the descriptor. This makes you think I am unhelpful?
It's unhelpful because command
listdescriptor doesn't list any private data (e.g. private key and master private key). See
https://bitcoincore.org/en/doc/28.0.0/rpc/wallet/listdescriptors/.
If you decided it was unhelpful you should have offered mentorship. Why did you think a neutral trust is helpful? The took it to make screenshots, if you applied a fraction of it to offer advice it would have been helpful.
