Buat teman2 yg merasa lemot klo pke internet dengan OS Ubuntu ini saya punya sedikit troubleshot

untuk menambahkn kecepatan akses internet di OS ubuntu ... langsung aja yah :

1.Masuk ke terminal

2.Masuk ke user root ... syntagnya sudah tau kn ... sudo su ... dan masukkan password

3.edit konfigurasi di  /etc/sysntl.conf .. ketik  nano /etc/sysctl.conf

4.Paste syntax2 ini di bagian paling bawah :

# 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
 

setelah itu di save yah.

dengan kombinasi ctrl+x ... kemudian Enter

5.kemudian ketik :
  sysctl -p

6.Supaya lebih krasa  beneran ketik /etc/init.d/networking restart dan enter

7.Supaya lebih krasa ketik exit .. kemudian enter

8.Rasakan bedanya

 Silahkan dicoba .....
