In reality, I'm trying to test the performance in my squid3 branch under different situations and I need a way to simulate additional network latency.
FreeBSD "dymmynet" has good support for this kind of things on a packet level, see the Polygraph documentation for configuration examples.
Also recall seeing a Linux module for simulating network latency and packet loss but I don't remember where. Looking. There is several approaches to packet level latency simulation on Linux:
* the shaper module
* the delay interface queue policy
* Iptables QUEUE with Countertrace <http://michael.toren.net/code/countertrace/>
* NIST Net <http://snad.ncsl.nist.gov/nistnet/>
And I am sure there is several other alternatives as well. This is just the results of a quick 2 minutes search.
