This is FreeRDP's in-process RDP client + screen encoding. +- **Latencies stayed flat.** Session creation p95 remained under 100ms from 1 to 100 sessions — no degradation. +- **Zero errors.** Every session created and connected successfully at every concurrency level. +- **6 GB headroom remaining** at peak on a 16 GB machine.

This confirmed the linear ~158 MB/session scaling for guacd and validated that 16 GB was needed for 100 sessions. + +## Bottleneck Analysis + +### 1. guacd memory (primary bottleneck) + +Each RDP session runs FreeRDP in-process within guacd, consuming ~158 MB. This is the hard ceiling on concurrent sessions. For SSH sessions (no FreeRDP), guacd uses ~2-5 MB per session — roughly 30x more efficient. + +**Scaling formula:** +`max_rdp_sessions ≈ (total_ram - 2 GB for OS - 50 MB for rustguac) / 158 MB` + +| Server RAM | Max RDP sessions (est.) | +|------------|------------------------| +| 8 GB | ~38 | +| 16 GB | ~88 | +| 32 GB | ~190 | +| 64 GB | ~392 | + +### 2. Address book Vault reads (API bottleneck) + +`GET /api/addressbook` performs sequential HTTP calls to Vault: 1 LIST + N folder GETs + N entry LISTs + M entry GETs. At 1000 entries this takes ~2.4s. Not a session bottleneck but affects page load time. + +**Optimisation opportunities:** +- Parallel Vault fetches with `tokio::join_all` +- Short TTL cache (30-60s) for address book data +- Pagination for large folder listings + +### 3. Non-bottlenecks + +- **rustguac CPU/memory:** Negligible. The WebSocket proxy is two tokio tasks per session forwarding bytes through an 8 KB buffer. +- **rustguac file descriptors:** 351 at peak, well under default limits. +- **Session creation latency:** Flat at all concurrency levels. guacd handshake is fast. +- **Network:** ~10 KB/s per idle session. Active sessions with screen changes: ~100-500 KB/s typical for RDP. +- **SQLite:** Not in the hot path. Only used for auth/token validation. +- **tokio runtime:** 9 threads at peak for 200 async tasks (2 per session).
