cisco packet tracer simulation

[Vin25]

hi, I need help simulation high latency for ICMP , http and VOIP in cisco packet tracer. Basically what I'm trying to do is create two same topology where one is better than the other. But I do not know how to simulate the bad one by giving it very high latencies. How do I do that? any suggestions? you guys can try to do it. the file is attached below.

Btw pc/laptops at Newark and Branch Office only works for the http (in the pkt below).

the following is other topology where it is the better one. It has few qos configurations.

For example, if i go to PC4 and browse yahoo.com, it should take longer time than it already shows. Because now its shows 0.022; something close to that. But i want it to be longer like more than 0.100 if possible. That is for HTTP. But for ICMP and VOIP is the same. All the time u can check in the simulation mode. When i call ip phone3 to ip phone6 it take 0.023 but i want it to be longer. ICMP if i ping somethin it should take longer too or introduce packet loss.
