# Resource Considerations & Performance
Performance of the AI Script Generation process depends heavily on the resources available to your **test node** and the configuration choices you make. Here are the general guidelines from Appvance.
### Headless vs non-headless browsers
You can run the AI browsers in **headless** or **non-headless** mode. Headless mode is recommended for increased performance and lower resource usage. As a rule of scale: if you can run **5 non-headless browsers**, you can likely run **10–15 headless browsers** with the same performance.
| Mode | Limiting factor | Typical scale |
|---|
| >**Non-headless** | >Memory (RAM) on the test node | >16 GB → 5 browsers · 32 GB → 10 · 64 GB → 20 |
| >**Headless** | >CPU speed and thread count | >10–15 browsers at 2.4–2.6 GHz base |
**Tip:** if performance is slow, try **reducing the number of browsers**. Running more browsers than the machine can handle makes the whole AISG process slower — not faster.
### Delay between requests
**Delay Between Requests (ms)** is an execution option that determines how long AIQ waits for the application to load before reporting a failure while navigating. A longer delay gives the application more time to respond. As a side effect, higher delays can let you run **more browsers** (some go to sleep while waiting). For example: 10 browsers work best at 0 ms delay, but at 20 ms you may run 15. This is not a direct correlation — **benchmark your own environment**.
### Types of applications
- **Static** — very static apps with few elements: up to **20 headless browsers** on a standard 8-core / 32 GB node.
- **Dynamic** — highly dynamic apps (moving elements, Shadow DOM, iframes): do some **basic benchmarking**.
### Basic benchmarking
1. Run a quick AISG execution — e.g. compare 10 headless vs 5 non-headless browsers.
2. Monitor memory and processor utilization.
3. Use the results to decide on the browser count for your real AISG run.
### AIQ limits
50
absolute max browsers (hard limit)
35–50
optimum browsers even with abundant resources
**Also note (AIQ 5.0):** AI blueprinting is supported only on **Windows test nodes**. Mobile blueprinting, Compare Blueprints, and the Generate Scripts option are disabled in 5.0 — use the Coverage Map DS generation instead.
