If you want to optimize a very slow Internet speed to make it faster, there is the step!

Step 1: Install TCPOptimizer
If your loading speed as well as downloads are taking too long? You have to get the program (SG TCP Optimizer).

Step 2: Using DNS Servers
There are 3 versions of DNSes to be optimized.
OpenDNS:
Preferred DNS server: 208.67.222.222
Alternate DNS server: 208.67.220.220

Google DNS:

Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4

Cloudflare DNS:

Preferred DNS server: 1.1.1.1
Alternate DNS server: 1.0.0.1

Step 3: Use uBlock Origin extension

If you want this extension for Chrome or Firefox, it makes the websites load 25% faster. Also, to boost the download speed in Chromium, you have to enable the "Parallel downloading" in chrome flags.
