|

By default, there is no limitation on the number of concurrents requests that a server/cluster processes at the same time. However, it is possible to impose such limitation using the API subsystem. Read more about throttling limitation in MinIO server [here](https://github.com/minio/minio/blob/master/docs/throttle/README.md).

Platforms like Kubernetes *do not* forward traffic to a pod until its readiness probe is successful.

### Configuration example
|
||||
|
||||
Sample `liveness` and `readiness` probe configuration in a Kubernetes `yaml` file can be found [here](https://github.com/minio/minio/blob/master/docs/orchestration/kubernetes/minio-standalone-deployment.yaml).
|
||||
|
||||
### Configure readiness deadline
|
||||
Readiness checks need to respond faster in orchestrated environments, to facilitate this you can use the following environment variable before starting MinIO
|
||||
|
||||
```
|
||||
MINIO_API_READY_DEADLINE (duration) set the deadline for health check API /minio/health/ready e.g. "1m"
|
||||
```
|
||||
|
||||
Set a *5s* deadline for MinIO to ensure readiness handler responds with-in 5seconds.
|
||||
```
|
||||
export MINIO_API_READY_DEADLINE=5s
