Well, It's true latency is high but around 160ms tops if you stay at capital cities (Sp/Rj). The main problem is that latency inside the country is already huge if you compare to the one going oversea. Good news is that a new cable will be deployed connecting Sp directly to Nyc. That's why we chose to focus our droplets at Nyc datacenters. This could drop the latency up to 30%.
