description: Performance measures for etcd v3
|
|

|
|
|
|
## Physical machines
|
|
|
|
GCE n1-highcpu-2 machine type
|
|
|
|
- 1x dedicated local SSD mounted under /var/lib/etcd
|
|
- 1x dedicated slow disk for the OS
|
|
- 1.8 GB memory
|
|
- 2x CPUs
|
|
- etcd version 2.2.0
|
|
|
|
## etcd Cluster
|
|
|
|
1 etcd member running in v3 demo mode
|
|
|
|
## Testing
|
|
|
|
Use [etcd v3 benchmark tool][etcd-v3-benchmark].
|
|
|
|
## Performance
|
|
|
|
### reading one single key
|
|
|
|
| key size in bytes | number of clients | read QPS | 90th Percentile Latency (ms) |
|
|
|-------------------|-------------------|----------|---------------|
|
|
| 256 | 1 | 2716 | 0.4 |
|
|
| 256 | 64 | 16623 | 6.1 |
|
|
| 256 | 256 | 16622 | 21.7 |
|
|
|
|
The performance is nearly the same as the one with empty server handler.
|
|
|
|
### reading one single key after putting
|
|
|
|
| key size in bytes | number of clients | read QPS | 90th Percentile Latency (ms) |
|
|
|-------------------|-------------------|----------|---------------|
|
|
| 256 | 1 | 2269 | 0.5 |
|
|
| 256 | 64 | 13582 | 8.6 |
|
|
| 256 | 256 | 13262 | 47.5 |
|
|
|
|
The performance with empty server handler is not affected by one put. So the
|
|
performance downgrade should be caused by storage package.
