Optimizing PPPoE Speedy with MTU

By

Iseng2 wa googling tentang koneksi speedy.. ada salah satu yg buat gw tertarik buat nyobanya. Yaitu setting MTU untuk koneksi pppoenya, secara default MTU kita di 1400. Kalo kita dapet value yg cocok, bisa mempercepat koneksi kita loh.

Nah skrng kita coba trial dan error dulu, MTUnya distandart dulu. kita hanya menggunakan fasilitas ping.

Command di windows xp :

ping -f -l 1500 www.yahoo.com

Command di Ubuntu :

ping -M do -s 1500 www.yahoo.com

Kita mulai dari nilai terbesar yaitu 1500, coba perlahan turun kan sedikit2 sampai dapat value yg mantab.

Ini wa coba di ubuntu ane.. lihat perbedaan pingnya
