Simulate Latency / increase latency?

[TexasDave]

I need to do some testing and am wondering if there is a way to increase my latency or simulate high latency? Open to doing this in Merlin or in a Merlin addon?

I saw a post about leveraging VMs to do this but hoping to do something on the router. Happy if it affects everything short term or if I can do it on the client level?

Or happy to use another method?

Trying to test a website with low quality of service / high latency.

Many thanks for ideas or pointers.

Use a computer with one core. And/or 1GB RAM.

Still open to any router tricks or tips to do this but found some possible proxy servers or other tools I may be able to use. Thanks!

I see there is a way to delay outgoing packets from the network. Is there a way to delay incoming packets?

I've never used netem myself but that link has a FAQ called "How can I use netem on incoming traffic?"
