# Consumer session balancing

Sometimes consumers get overwhelmed by the number of messages they receive. VerneMQ can loadbalance between multiple consumer instances subscribed to the same topic with the same ClientId.

## Enabling Session Balancing

To enable session balancing, activate the following two settings in vernemq.conf

```
 allow_multiple_sessions = on
 queue_deliver_mode = balance
```

{% hint style="info" %}
Currently those settings will activate consumer session balancing globally on the respective node. Restricting balancing to specific consumers only, will require a plugin. Note that you cannot balance consumers spread over different cluster nodes.
{% endhint %}
