Performance Measurements
This page documents load test results for different releases of cardano-rosetta-java, evaluating performance across various deployment scenarios.
Service Level Agreements (SLAs)
Our performance evaluation is based on the following Service Level Agreements (SLAs), which define the acceptable thresholds for production environments:
- Response Time: A p99 of less than 1 second is the target for all standard API endpoints.
- Error Rate: A non-2xx response rate of less than 1% is considered acceptable.
In specific high-load scenarios, such as querying addresses with hundreds of thousands of transactions, these SLAs may be adjusted to assess system stability under extreme conditions. Any such adjustments are noted in the relevant test results.
Load tests are conducted using Apache Bench (ab) with a ramp-up strategy, progressively increasing concurrency to a predefined ceiling of 500 simultaneous requests.
To better understand the environments in which these results were obtained, please refer to our hardware profiles documentation.

| 2 | /account/coins | 500 | 184ms | 402ms | 0 | 0.00% | 5964.08 |
Pruning Disabled (REMOVE_SPENT_UTXOS=false)
For this specific test with pruning disabled, the standard 1-second Service Level Agreement (SLA) is not achievable. Therefore, the SLA was adjusted to 10 seconds to evaluate system stability under extreme load, even with degraded performance.

Pruning Disabled (REMOVE_SPENT_UTXOS=false)
For this specific test with pruning disabled on an address with ~1.6M transactions, the standard 1-second Service Level Agreement (SLA) is not achievable. The SLA was adjusted to 10 seconds to evaluate system stability under extreme load. The results for /account/balance at concurrency 1 are reported despite slightly exceeding this adjusted SLA to provide a transparent view of the performance boundary.
