Recentemente, considero comprar meu terceiro servidor VPS<\/a> e a velocidade do ping \u00e9 uma das preocupa\u00e7\u00f5es. Eu tenho um ping relativamente alto (cerca de 250 ms) do Reino Unido para o servidor localizado em Cingapura, o que torna a digita\u00e7\u00e3o de comandos no console SSH um pouco desagrad\u00e1vel.<\/p>\n

Felizmente, alguns provedores de VPS, como Vultr<\/a>, fornecem endere\u00e7os IP<\/a> para seus 15 locais, para que voc\u00ea possa testar a velocidade do ping. Como fazer isso automaticamente sem digitar o comando ping<\/a> toda vez?<\/p>\n

localiza\u00e7\u00f5es de servidores vultr globalmente<\/p>\n

Voc\u00ea pode encontrar um exemplo de script PHP<\/a> para fazer isso:<\/p>\n

Em seguida, com base na string de sa\u00edda, usamos o testador de regex preg_match<\/strong> e calculamos a m\u00e9dia desses 3 pings. Por fim, ordenamos o array por valores. Abaixo, os testes de velocidade do Reino Unido, EUA e Cingapura para locais globais s\u00e3o realizados e \u00e9 surpreendente que o ping entre EUA (Leste) e Reino Unido seja inferior a 80ms.<\/p>\n
