Example: Limit a MinIO cluster to accept at max 1600 simultaneous S3 API requests across all nodes of the cluster.

```sh
export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
minio server http://server{1...8}/mnt/hdd{1...16}
```

or

```sh
mc admin config set myminio/ api requests_max=1600
mc admin service restart myminio/
```

and pauses up to '250ms' per object when the system has `max_io` number of concurrent requests. It is possible to adjust the `max_sleep` and `max_io` values thereby increasing the healing speed. The delays between each operation of the healer can be adjusted by the `mc admin config set alias/ heal max_sleep=1s` and maximum concurrent requests allowed before we start slowing things down can be configured with `mc admin config set alias/ heal max_io=30` . By default the wait delay is `250ms` beyond 100...

MINIO_NOTIFY_POSTGRES_COMMENT              (sentence)           optionally add a comment to this setting
MINIO_NOTIFY_POSTGRES_MAX_OPEN_CONNECTIONS (number)             maximum number of open connections to the database, defaults to '2'
```

> NOTE: If the `max_open_connections` key or the environment variable `MINIO_NOTIFY_POSTGRES_MAX_OPEN_CONNECTIONS` is set to `0`, There will be no limit set on the number of

fs.s3a.fast.upload=true # Turn on fast upload mode

fs.s3a.multipart.size=512M # Size of each multipart chunk
fs.s3a.multipart.threshold=512M # Size before using multipart uploads
fs.s3a.socket.recv.buffer=65536 # Read socket buffer hint
fs.s3a.socket.send.buffer=65536 # Write socket buffer hint
fs.s3a.threads.max=2048 # Maximum number of threads for S3A
