Kaalun hiljuti oma kolmanda VPS-serveri<\/a> ostmist ja pingi kiirus on \u00fcks murekohti. Mul on suhteliselt k\u00f5rge ping (umbes 250 ms) \u00dchendkuningriigist Singapuris asuvasse serverisse, mis muudab SSH-konsoolis k\u00e4skude tippimise pisut ebameeldivaks.<\/p>\n

\u00d5nneks pakuvad m\u00f5ned VPS-i pakkujad, nt Vultr<\/a>, oma 15 asukoha jaoks IP-aadresse<\/a>, nii et saate testida pingi kiirust. Kuidas seda automaatselt teha ilma iga kord ping<\/a> – k\u00e4sku tippimata?<\/p>\n
