Gas Snapshot

[wjmelements]

Reviewer @aarshkshah1992

Gas roughly measures the burden of operations on the network, so we want to reduce it.

Although filecoin gas won't be the same as Ethereum, measuring the ethereum gas will provide a way to know to what extent a change reduces gas.

Changes

• add .gas-snapshot
• add workflow to check the .gas-snapshot

looks like creating new rails is especially expensive

[aarshkshah1992]

It's just a bunch of memory write operations and an event emission. Any idea why this would be ? It's all in the createRail function if you wanna take a look. (But this is not a high priority right now, totally your call man).

Is there an easy way to update that?

@wjmelements Wdym ? You can just open a PR to update those numbers as the doc lives in this repo (pretty sure I'm missing something here).

For my own understanding:

Dosen't it also help increase network revenue for token holders if the gas token is the same as chain token ?
All for decreasing gas as it improves UX but I've never been able to reconcile improving UX for end-users with decreasing revenue for token holders in my mental model.

It would be best if we could run a script (such as forge snapshot) to update those numbers automatically. Then it would be easy to see how much a PR impacts gas.

If the payments are more efficient, the network can do more of them, and we can supply them more sustainably and competitively. This is the supply side.

If payments are too expensive, existing and potential users will choose cheaper alternatives. This is the demand side.

Thanks for your replies man ! We don't have this setup right now. But it would be awesome to have it. Please feel free to raise a PR (can do it as part of this PR as well) and we can then merge the whole thing together 👍
