Why is the GET method faster than POST in HTTP?

Question

I am new to web programming and just curious to know about the GET and POST methods of sending data from one page to another.

It is said that the GET method is faste

Answer 1

Looking at the http protocol, POST or GET should be equally easy and fast to parse. I would argue, there is no performance difference.

Take a look at the raw HTTP headers

http GET

GET /index.html?userid=joe&password=guessme HTTP/1.1
Host: www.mysite.com
User-Agent: Mozilla/4.0

http POST

POST /login.jsp HTTP/1.1
Host: www.mysite.com
User-Agent: Mozilla/4.0
Content-Length: 27
Content-Type: application/x-www-form-urlencoded

userid=joe&password=guessme

From my point of view, performance should not be considered when comparing GET and POST.
