Upgradeable gas cost overhead?

[Met]

How exactly does the cost of contract calls increase by making a contract upgradeable?

I think this consideration should be included already in the upgradeable introduction article, now there is no mention.

Hi @Met,

Welcome to the community

Thanks for the feedback, I have created issue https://github.com/OpenZeppelin/docs.openzeppelin.com/issues/241 for this.

As for the actual overhead, pre-Istanbul price changes the following test was done:

Gas overhead for proxied function call

Say, have you done any estimates on gas overhead for proxied function call compared to call directly to the corresponding function in the logic contract? If so is there any variance in or dependency of the overhead to be aware of when developing smart contracts with ZeppelinOS?

Great, thank you! I was searching the KB for it but failed to find the answer you linked.

You can deploy a test case on a testnet and compare the gas needed for both flavors (upgradable and non upgradable)
