Tips Mempercepat Koneksi Internet Ubuntu tanpa software


  1. Buka Terminal
  2. Backup terlebih dahulu file sysctl.conf jika terjadi error sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup jadi file backup anda adalah sysctl.conf.backup
  3. Edit file sysctl.conf : sudo gedit /etc/sysctl.conf
  4. Masukkan kode berikut di akhir file yang anda edit tadi :
    ---------------------------------------------------------------------
    # increase TCP max buffer size setable using setsockopt()
    net.core.rmem_max = 16777216
    net.core.wmem_max = 16777216
    # increase Linux autotuning TCP buffer limits
    # min, default, and max number of bytes to use
    # set max to at least 4MB, or higher if you use very high BDP paths
    net.ipv4.tcp_rmem = 4096 87380 16777216
    net.ipv4.tcp_wmem = 4096 65536 16777216
    # don't cache ssthresh from previous connection
    net.ipv4.tcp_no_metrics_save = 1
    net.ipv4.tcp_moderate_rcvbuf = 1
    # recommended to increase this for 1000 BT or higher
    net.core.netdev_max_backlog = 2500
    # for 10 GigE, use this, uncomment below
    # net.core.netdev_max_backlog = 30000
    # Turn off timestamps if you're on a gigabit or very busy network
    # Having it off is one less thing the IP stack needs to work on
    #net.ipv4.tcp_timestamps = 0
    # disable tcp selective acknowledgements.
    net.ipv4.tcp_sack = 0
    #enable window scaling
    net.ipv4.tcp_window_scaling = 1
    ---------------------------------------------------------------------
  5. Simpan file
  6. Masukkan perintah ini di terminal : sudo sysctl -p
  7. Untuk menonaktifkan cukup hapus kode yg elah dimasukkan tadi di file sysctl.conf
  8. Sekarang saatnya untuk browsing.
