Benchmarks
Milestone 1
This benchmark compares gas used for CBOR serialization written in solidity with other calls like a simple transfer of FIL or a ERC20 transfer call written using AssemblyScript SDK developed by Zondax.

This benchmark compares gas used for CBOR serialization using precompiled contracts with other calls like a simple transfer of FIL or a ERC20 transfer call written using AssemblyScript SDK developed by Zondax. It also includes Milestone 1 benchmark result.
Benchmarks
These values were generated by running the smart contracts on the integration suite written in rust by Filecoin. The current version used can be found here 🔗.

| ERC20-like token transfer (assemblyscript native) | 697,452 |
| Simple send (native) | 413,868 |
| --------------------------------------------------|----------------------|
When serializing in a precompiled contract we are using less gas than when serializing inside a Solidity contract. However, the gas usage is still significant. The use of the opcode STATICCALL seems to cost the most and the rest seem to be memory.
Notes
- The ERC20-like token smart contract was written using AssemblyScript SDK. It can be found here 🔗
- The empty call could be use as the baseline, as it just call a precompiled actor that does nothing. This should be the less expensive call.
- The "simple send" is a FIL token transfer.
