When playing online games, a good practice is to close applications and programs that are running in the background. This helps to reduce load on your computer as well.
The most effective method to close any program and executable file from your computer are through the task manager. A picture of which is shown below
One more extra thing
Turn off your torrent if you are using one. That thing is your bandwidth’s worst nightmare

Rate is the limit of how much download bandwidth should be given to CSGO. Measured in Bytes, the default rate for CSGO is 80,000. This maximum value is capped at 128,000. So unless you are playing on a dial-up connection, which we wish you won’t then you should set your value to 128000.
Recommended Value: rate 128000

The number of packets that are sent by your computer to the game server. The default value is 64, and the maximum limited to 128. If you have a stable 100+ FPS in game, then set your value to 128, else it should remain the same.
Recommended Value: cl_cmdrate 128

This is the number of packets that your computer receives from the server. Similar to cl_cmdrate, the default value is 64 and is capped at 128. Make sure to put the same value as you had from cl_cmdrate
Recommended Value: cl_updaterate 128

This command sets the interpolation amount in CS:GO. Though decreasing interpolation can help reduce your CS:GO lag, having an absolute zero is not possible. You can set it to 0, and the command will automatically set the number to the least possible amount, e.g. 0.01.
Recommended Value: cl_interp 0

Sets ratio for the above interpolation time.It is recommended to use 2
Recommended Value: cl_interp_ratio 2
