• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.

♻️ This comment has been updated with latest results.

Also, commit d2b667a has an odd description. I don't think that my name is worth to be mentioned as the main commit message. According to our coding standards we want to put What a commit is about in the first line.

[ch1bo]

Don't disable tests and we need to clarify that this is a breaking change on the scripts as well.

[ch1bo]

Also, updating to latest plutus compiler seemed to have quite some effect on the script performance:

• Overall slight increase in script size
• 50% less memory usage in close and contest transactions
• abort slightly less memory usage and may be possible with 6 parties now
• .. maybe more (just had a quick look)

I need you to be aware of this and also document these changes in the changelog along with the breaking change on the scripts before we can merge this.

[ch1bo]

Addressed the must-haves myself now.
