title: Benchmarking etcd v2.1.0
|
|
---
|
|
|
|
## 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 2.1.0 alpha
|
|
|
|
## etcd Cluster
|
|
|
|
3 etcd members, each runs on a single machine
|
|
|
|
## Testing
|
|
|
|
Bootstrap another machine and use the [hey HTTP benchmark tool][hey] to send requests to each etcd member. Check the [benchmark hacking guide][hack-benchmark] for detailed instructions.
