I know Egypt still does not have fast internet connections, so, let's say that I want to mimic a speed of 512 kbps instead of 3.5 MB I believe if I used your example I should get an exact result on how much should I delay the request on the resolve DNS state or connect. Will that work and simulate the speed that I want?
If you want to be technical about it - DNS requests and TCP handshakes exchange multiple IP packets back and forth. Those packets take up X bytes to transmit. So, if you want to simulate a 512kbps connection during the DNS resolve and TCP connect stages, then convert X to bits, multiply by 1000, and divide by 512kb, and that will be how many milliseconds minimum you need to sleep. It is just basic math.
