What free programs are there to emulate a narrow network channel?

Question

Software testing

I have a client server application. The sql server is on a different machine, but on the same network. It is necessary to compare the operation of the system on the old and new versions, but since the ping is very short, the difference is not noticeable and it is necessary to increase the ping between computers. Please advise a utility for this purpose

Answer 1

In the router, limit the speed or simply "hammer" the channel.
