Create a cost analysis tutorial / resource

[leighmcculloch]

We don't currently have a page that talks concretely and practically with examples for how to evaluate the cost of a contract, and how to improve the efficiency of contract functions.

This page should probably be in the form of a tutorial with a concrete example of how to view the cost of executing a contract function, then making a change to improve the efficiency of the contract, then re-running the contract and viewing the improved cost.

The tutorial should ideally touch on the derived cpu/mem costs as well as the individual costs that lead to the derived values, so that folks know how to identify where their costs are coming from.

Dependent on:

• Fix --cost parameter on invoke command stellar-cli#889.

I would be happy to help with this as well.

@kalepail Do you have something about that you've written your blog post that we could repurpose here? Thanks in advance!

I've got this

• https://kalepail.com/blockchain/show-me-the-bill-part-1
• https://kalepail.com/blockchain/show-me-the-bill-part-2

Not sure that's quite what Leigh has in mind though which is more scenarios and and tabular facts vs code walkthroughs.

This guide was created for the bounty: https://developers.stellar.org/docs/build/guides/conventions/analyzing-smart-contract-cost, does this help solve this issue?
