Delightfully hardcore indeed!

But of course you don't have to buy a rack of servers for testing, you can rent it. Servers are a quickly depreciating asset, why invest in them?

Why would replaying data for testing be "Delightfully hardcore indeed!". That's how people program in general, they run the same data through their program.

I don't think they are a quickly depreciating asset compared to the price of renting, but you would want total control over them in this scenario anyway.

I thought that the hardcore part is taking the data from the switch to account for the network latency.

Replaying data isn't hardcore. Buying a dedicated server and running it through a dedicated switch just to gather precise timing info is.

You'd want it to be the exact same hardware as in production, for one.
