# Improve robot performance

### How can I improve robot performance?
A single robot execution will run from start to finish in a single processing thread, meaning that it will select one button at a time and visit one page at a time.

To increase efficiency, you can split your robot into two: 
* one that gets all the URLs of the pages to visit and
* one that takes those URLs as input. 

This allows the robot to visit pages concurrently (up to your account's concurrency limit), significantly speeding up execution time.

:::(Info) (Note)
Be aware that increasing concurrency should be done with care and respect for the target site to not interrupt services or cause excessive load/stress on the site. 
:::

For smaller sites, stay below a maximum of 10 concurrent robots. For sites that experience larger amounts of traffic, you can probably go a bit higher. 

Always read the terms and policies for the site you're scraping to ensure you're complying with their terms.

#### How do I disable images, stylesheets and Javascript?
You cannot globally disable images, stylesheets or javascript with a single click, but you can prevent specific network requests which will speed up load time.

#### How to block or ignore network requests
Blocking network requests for certain unnecessary elements can improve robot performance. 

When using the robot editor,
1. Select the **Network** tab to get an overview of the network traffic involved in a page request. 
2. Select the URL icon to mark scripts and elements for blocking or ignoring. 
3. Here, you can block/ignore specific URLs/file types or entire domains.

By default, we block Google Analytics and other tracking scripts; we don't want to skew the analytics data of any Web site we scrape.
