# Settings - Execution Speed

## What is Extraction Speed Adjustment?

Popular websites with global traffic often run systems to block abusive traffic. If your data collection speed with Listly is too fast, the website might flag it as abusive behavior and block your access. In the worst case, your IP address could be permanently banned. To prevent this, **Listly lets you control your collection speed**.

{% hint style="success" %}
**The faster your collection speed, the higher the chance of IP blocking.**

If you run into this issue, Listly Enterprise can help. With `Premium Proxy Purchase` + `Auto Retry` features, you'll use a fresh, high-quality IP address for each request, and if collection fails, the system automatically retries with a different IP.

## How to use it

### Slowing down collection speed

Data collection speed refers to how many URLs are collected simultaneously. So **speed 15** means collecting up to 15 web pages at once. From the target site's perspective, this can look like a traffic attack. Many sites will ask you to verify you're human or permanently block your IP if you visit too many pages in a short time. This leads to extraction failure.

To prevent and address this, Listly lets you manually adjust extraction speed. We recommend the minimum values of 1 or 2, which mimics the speed of actual human browsing. **The slower your collection speed, the lower the chance of extraction failure.**

Head to your Listly Databoard and check the **Extraction Speed** bar in the top right corner, as shown in the screenshot below.

Adjust to your desired speed and click the **\[Yes]** button.

Selecting speed 1 means the slowest collection, while selecting 15 means the fastest. It's the difference between collecting 1 URL at a time versus 15 URLs at a time.

If you want to **complete data collection quickly**, we recommend increasing extraction speed while using `high-quality proxies` to reduce blocking risk. Proxies are available as a separate purchase.
