```csharp
public int ActivationCountWeight
```

The importance of the current activation count to the silo.

```csharp
public int AvailableMemoryWeight
```

The importance of the available memory to the silo.

```csharp
public int LocalSiloPreferenceMargin
```

The specified margin for which: if two silos (one of them being the local to the current pending activation), have a utilization score that should be considered "the same" within this margin. 

- When this value is 0, then the policy will always favor the silo with the lower resource utilization, even if that silo is remote to the current pending activation.
- When this value is 100, then the policy will always favor the local silo, regardless of its relative utilization score. This policy essentially becomes equivalent to [PreferLocalPlacement](/orleans/docs/api/csharp/microsoft.orleans.core.abstractions/orleans.runtime.preferlocalplacement/).

## MaxAvailableMemoryWeight {#maxavailablememoryweight-b7fbffc1}

```csharp
public int MaxAvailableMemoryWeight
```

The importance of the maximum available memory to the silo.

```csharp
public int MemoryUsageWeight
```
