Suspiciously large gas overhead #2

Open sirgarfieldc opened 1 year ago

sirgarfieldc commented 1 year ago

I am testing this repo out and I am observing around 2.8K gas overhead (difference between calling logic contract directly vs via proxy).

This is significantly larger than the numbers below reported here https://forum.openzeppelin.com/t/a-more-gas-efficient-upgradeable-proxy-by-not-using-storage/4111

Proxy Gas cost Gas overhead
OpenZeppelin Transparent 29815 2770
Dharma Beacon 29752 2707
EIP-1882 UUPS 28679 1634
Storageless Beacon 28629 1584

I am wondering if there is something that I did wrong.

My compiler setting:

Solc 0.8.17
via_ir = true
optimizer = true
optimizer_runs = 2000

Can other users share their overhead number ?

Thanks

The post is a few years old, its likely that the Ethereum protocol went through some changes that resulted in opcodes being priced differently

makes sense. but can you confirm if the 2.8k number is inline with what you currently observe in your usage ?
