Turnstile and old computers

I’m just a user, and didn’t find any helper on other place so… I’m user from a website that use cloudflare services. i guess they’re using turnstile for anti bot, there is a sesion on website that user can claim codes, and this depends entirely on speed. And for a reason idk on a older computer this auto captcha verification loses every time. idk if it’s intentional i just want to know how turnstile service works, i don’t understand why i’m losing the claim so often. Why can i do to agilize this verification from turnstile?
