# Reference Setup, Performance, Scalability, and Sizing Guidelines | ||
|
||
In this document, we present the reference setup, performance, scalability, and sizing guidelines when using the Longhorn storage system. | ||
In practice, users deploy Longhorn in a vast array of different cluster specifications, making it impossible for us to test all potential setups. | ||
Therefore, we will select and test some typical environments for users' reference. | ||
By providing these references, users can gain insight into how Longhorn would perform in a similar cluster specification. | ||
