Speed tx and UI/UX

the time needed every tx is 10-30 minutes, isn’t that too long?
one of the advantages of crypto is speed and practicality, if it stays like this it’s a shame
I hope this is only on the testnet, on the mainnet hopefully it won’t take more than 5 minutes

talking about UI/UX, I scroll up and down the website, it feels delayed and heavy
then the colors and designs are very monotonous
