Dragonfly shows a comparable performance:
1. SETs (`--ratio 1:0`):
| Redis | DF |
| -----------------------------------------|----------------------------------------|
| QPS: 159K, P99.9: 1.16ms, P99: 0.82ms | QPS:173K, P99.9: 1.26ms, P99: 0.9ms |
| | |
2. GETs (`--ratio 0:1`):
| Redis | DF |
| ----------------------------------------|----------------------------------------|
| QPS: 194K, P99.9: 0.8ms, P99: 0.65ms | QPS: 191K, P99.9: 0.95ms, P99: 0.8ms |
The benchmark above shows that the algorithmic layer inside DF that allows it to scale vertically
does not take a large toll when running single-threaded.
However, if we take a bit stronger instance (m5.xlarge), the gap between DF and Redis starts growing.
