• 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.

3-nodes Scenario

A rather typical setup, with 3 nodes forming a Hydra head.

Number of nodes	3
Number of txs	900
Avg. Confirmation Time (ms)	68.008361632
P99	217.75547400999997ms
P95	148.67382434999996ms
P50	56.213803ms
Number of Invalid txs	0

Baseline Scenario

This scenario represents a minimal case and as such is a good baseline against which to assess the overhead introduced by more complex setups. There is a single hydra-node d with a single client submitting single input and single output transactions with a constant UTxO set of 1.

Number of nodes	1
Number of txs	300
