If someone ceates a sustained transactions summing to 512kB on the dogecoin-testnet this would simulate demand for 5 MB blocks on a bitcoin-testnet. I need help in monitoring this. We can monitor node-count, and transaction pool size, and perhaps other factors. I have a million test-dogecoins. This effort requires a dogecoin transaction maker script and a server (virtual server to execute them).
If you want to volunteer post here.

in short.. bitcoin runs on a raspberry Pi(1gb ram) .. and so a normal desktop which on average has 8gb ram as standard wont be a problem (we are not stuck with technology of a decade ago)... but lets say we were...
even a cheap nasty 2gb ram desktop computer from 2006 would be more powerful than todays raspberry pi in every way by ATLEAST a factor of 2 thus able to hand bitcoisn 2mb proposals... so todays technology could handle 8mb.. but then we are not concerned with the hardware, but the internet once things start getting to 8mb+.. so for now 8mb is a little too much for general population
