I need to calculate the effect of DoS on factors such as http latency. I tried tools like echo ping but it does not give me the tcp latency time with respect to a remote host. For example,

hping/hping2 is a nifty lil tool for crafting just about any
TCP/UDP/ICMP Packet you can imagine. It gives statistics also. But it
will not tell you how long it takes to answer an HTTP request.
There are a few HTTP stress testing packages, notably hammerhead and
siege.
