Does daisy chaining two routers together make the network slower?

I have been researching some methods of daisy chaining two routers and one modem together, for a public and a private network for my small business. I came across this post: http://www.tomshardware.com/forum/31706-42-router-modem where it says I can connect it up like this:
[modem](wan)<-- wire -->(wan)[router #1](lan)<-- wire -->(wan)[router #2]
Click to expand...

With that setup, router#1 would be the public network and router#2 would be private, now what I don't understand is if both routers would be slowed and/or would router#2 be slowed?

In real life uses likely neither would be slowed enough for you to tell.

If you had a 10g internet circuit and router 1 and router 2 were connected with a 1g cable then router 2 would only get 1g....and be slowed ?

There is some overhead in the NAT so because the users behind router 2 are having to have their data NAT 2 time very technically it will take longer. As fast as modern routers are you would have a huge problem measuring this delay. It is likely under 1ms.

Your internet connection always tends to be the bottleneck. With a quality routers you likely could transfer data between any devices at close to the 1g cable speeds.
