Simulating Slow Network on Virtual Machines

We needed to simulate that our data frameworks will work over a slow network link. There is a VMWare configuration option to limit a virtual NIC to a certain bandwidth. Just edit the VM’s .vmx file and enter the speed in KB/s:

ethernet[n].rxbw.limit = 100
ethernet[n].txbw.limit = 100

There are a lot more configuration options you can include like drop rate, etc.
