Low performance in my website country, good performance elsewhere

I’m having a weird issue with my website https://largoarquitetura.com.br/

We changed the company branding, name, etc. recently. Since is all wordpress, i simply copied the old website into the new domain, and had to reconfigure Cloudflare. I’ve maintained all the same specs, is the free plan with the AOP for wordpress.

The last website had a decent A 90% performance on general speedtests. After the migration the new website hits terrible performances of E - F scores when testing in Brazilian servers, while testing in another countries it gets an acceptable B grade, wich is way better but still a little worse than previously.

Any ideias in what can be happening and how can i make the performance good in BR servers, where the business is located?

Olá,

O próprio teste do GTMetrix pode dar uma pista melhor do que está acontecendo, se você examinar o teste em mais detalhe. Por exemplo, onde tem Performance 34% x 78%, vc deve abrir cada um dos testes e compará-los, para ver por que motivo o GTMetrix está derrubando a nota de SP. Sabendo o que está por trás da nota ruim, fica mais fácil saber se o problema está no Cloudflare, no novo servidor de hospedagem.
