**What happens if the Maximum Replicas is set too high?**

The Compute Resource Request setting for the Armada always applies, so the game server has guaranteed resources, or is not scheduled to the Location at all.
To avoid degraded performance with reduced CPU availability, or OOMKills when memory is overcommitted, see [Resource Limits](../multiplayer-services/resource-management#resource-limits).

The term "OOMKills" uses inconsistent capitalization. In Kubernetes terminology, it's typically written as "OOMKilled" (past tense) or "OOM Kill" (two words). Consider changing "OOMKills" to "OOM kills" for better readability and consistency with standard terminology.

Suggested change
To avoid degraded performance with reduced CPU availability, or OOMKills when memory is overcommitted, see [Resource Limits](../multiplayer-services/resource-management#resource-limits).

More players increase the number of game servers that are `Allocated` at any given time, increasing the need for a larger Buffer Size.

The Buffer Size should be derived from the experience made with Proof of Concepts, Load Tests or Development environments,

The phrase "the experience made with" is awkward. Consider revising to "experience gained from" or "experience with" for clearer, more natural English.
