Struct BlockCmd

pub struct BlockCmd {
    pub shared_params: SharedParams,
    pub import_params: ImportParams,
    pub params: BenchmarkParams,
    pub enable_trie_cache: bool,
}

Benchmark the execution time of historic blocks.

This can be used to verify that blocks do not use more weight than they consumed in their WeightInfo. Example:

Let’s say you are on a Substrate chain and want to verify that the first 3 blocks did not use more weight than declared which would otherwise be an issue. To test this with a dev node, first create one with a temp directory:

$ substrate –dev -d /tmp/my-dev –wasm-execution compiled

And wait some time to let it produce 3 blocks. Then benchmark them with:

$ substrate benchmark-block –from 1 –to 3 –dev -d /tmp/my-dev –wasm-execution compiled –pruning archive

The output will be similar to this:

Block 1 with 1 tx used 77.34% of its weight ( 5,308,964 of 6,864,645 ns) Block 2 with 1 tx used 77.99% of its weight ( 5,353,992 of 6,864,645 ns) Block 3 with 1 tx used 75.91% of its weight ( 5,305,938 of 6,989,645 ns)

The percent number is important and indicates how much weight was used as compared to the consumed weight. This number should be below 100% for reference hardware.

Fields

shared_params: SharedParams

import_params: ImportParams

params: BenchmarkParams

enable_trie_cache: bool

Enable the Trie cache.

This should only be used for performance analysis and not for final results.
