Ok ok, I admit that I don’t know anything about lambda, ec2 etc. 
I’m still a bit confused about the comparison of tps numbers. It will be about the full stack I assume. I thought about the transaction size. Records differ in size, transactions can be on more than one record, etc. What does this number say at all, can you compare the quality of different applications this way? I think not http://www.neotys.com/blog/how-to-test-application-throughput/
