# Performance Tuning


## General guidelines

Microsoft's [Azure Storage Performance Checklist](https://learn.microsoft.com/en-us/azure/storage/storage-performance-checklist) should be considered for performance tips and design guidelines.

## Parallel message retrieval

Multiple parallel read operations are used to improve message throughput. The amount of parallel read operations is the square root of the configured [message processing concurrency](/nservicebus/operations/tuning.md). This value can be increased or decreased as needed by using the `DegreeOfReceiveParallelism` configuration parameter. See [Azure Storage Queues Transport Configuration](/transports/azure-storage-queues/configuration.md) on how to use this parameter.

> [!NOTE]
> Changing the value of `DegreeOfReceiveParallelism` will influence the total number of storage operations against Azure Storage Services and can result in higher costs.
