# Performance and Scale of Your Experience Cloud Site

With Experience Cloud, you can build a wide range of business-to-consumer (B2C) and business-to-business (B2B) applications. Examples include help forums, self-service portals, partner and channel websites, commerce and ticketing stores, and vaccination and appointment sites. Many of these sites require high user volume and they experience high traffic. We extensively test every standard template, component, and product for performance and scale, but standard capabilities can be extended to build highly customized experiences. Customizations, high user volume, and high traffic, and more can impact a site’s performance. Salesforce offers a range of features focused on supporting performance and scale regardless of your site’s requirements.

For some sites, we suggest enabling performance and scale optimizations to ensure that your site meets your performance needs. Work with your Salesforce representative to identify whether your site requires further configurations.

## Why You Should Evaluate Your Site

Site patterns determine which performance optimization tools are most beneficial. Do site visitors view or create content? Does your site support a high volume of users or a high amount of traffic? Does your site use many roles? Salesforce has created performance tools to address the impact of these different site patterns and more.

For examples of Experience Cloud site types and the traffic and transaction patterns most likely to affect performance, see [Which Performance Tools Do I Need Based on My Experience Cloud Site?](https://help.salesforce.com/s/articleView?id=experience.exp_cloud_site_use_cases.htm&release=264.0.0&type=5 "With Experience Cloud, you can build a wide range of business-to-consumer (B2C) and business-to-business (B2B) applications that have different performance and scale considerations and optimizations. This section outlines common scenarios, likely performance issues, and the best tools to optimize performance.")

## What Should You Keep in Mind?

Consider using performance tools if your site has [these attributes](https://help.salesforce.com/s/articleView?id=experience.exp_cloud_perf_considerations.htm&release=264.0.0&type=5 "Large-scale sites are more than just sites that support a large volume of users. Transaction loads, and heavy traffic patterns also impact the scale of a site. Large-scale sites can benefit from performance and scale optimization tools. Your account representative can advise you on which performance and scale optimizations to enable.").

- You expect a large number of site users
- You expect a high amount of traffic or transactions
- Your site requires many roles
- You’re customizing the standard Salesforce experience
- You’re using additional services at scale

## How Can You Improve Performance and Scale?

This table outlines the issues most likely to affect site performance and scale and shows the tools to use.

You can process more self-registrations and record creations per second when you process them in small batches, called micro-batches, instead of one at a time. After they’re submitted, the requests are collected into batches, and the batches are processed asynchronously. Processing transactions using micro-batching improves performance and keeps your site moving during heavy traffic spikes.")
