- Performance benchmarking
- Compatibility testing with Windows Server 2016/2019/2022

### Test Infrastructure Requirements
- Windows Server test environment with:
  - Failover clustering
  - RDMA-capable network adapters
  - DFS namespace
  - Multiple network interfaces

## Configuration Properties

```properties
# Lease configuration
jcifs.smb.client.useLeases=true
jcifs.smb.client.leaseTimeout=30000

        // Score interface for selection (higher is better)
        int score = linkSpeed;  // Base score is link speed
        
        if (rssCapable) score += 1000;   // Prefer RSS-capable
        if (rdmaCapable) score += 2000;  // Prefer RDMA-capable
        if (!ipv6) score += 100;         // Slight preference for IPv4
        
        return score;

Faire du code asynchrone signifie que le langage 💬 est capable de dire à l'ordinateur / au programme 🤖 qu'à un moment du code, il 🤖 devra attendre que *quelque chose d'autre* se termine autre part. Disons que ce *quelque chose d'autre* est appelé « slow-file » 📝.

### 8.2 Integration Tests
```java
@Test
public void testLeaseWithRealServer() throws Exception {
    // Requires SMB3 capable server
    CIFSContext context = getTestContext();
    context.getConfig().setProperty("jcifs.smb.client.useLeases", "true");
    
    try (SmbFile file = new SmbFile("smb://server/share/test.txt", context)) {

Le programme **serveur** (par exemple **Uvicorn** via **FastAPI CLI**) est capable d'interpréter ces en‑têtes, puis de transmettre ces informations à votre application.

Mais, par sécurité, comme le serveur ne sait pas qu'il se trouve derrière un proxy de confiance, il n'interprétera pas ces en‑têtes.

The **server** program (for example **Uvicorn** via **FastAPI CLI**) is capable of interpreting these headers, and then passing that information to your application.

But for security, as the server doesn't know it is behind a trusted proxy, it won't interpret those headers.
