Latency tests |
A suite of tests to determine message latency under load |
All tests were run on Amazon Web Services EC2 instances within the same region, running AWS Linux. For the cluster tests, Redis was used as a message bus.
| Single Node | Cluster | ||
|---|---|---|---|
| machine for deepstream servers | 1 EC2 c4.large | 1 EC2 c4.2xlarge | |
| deepstream servers | 1 | 3 | |
| client pairs | 250 | 750 | |
| ec2 t2.micro instances clients were distributed across | 2 | 6 | |
| message frequency per client | ~25ms | ~25ms | |
| duration of full load | ~3 min | ~12 min | |
| messages per second | ~10,000 | ~30,000 |
Average latency was 2.065ms ( machines being within same data centre )
Average latency was 0.999ms ( machines being within same data centre )
