## File system performance
<a name="kendra-file-performance"></a>

When you add an FSx for Windows File Server file system as a data source, Amazon Kendra crawls the files and folders on the file system on a regular sync frequency to create and maintain its search index. (You can select the sync frequency when you establish the integration.) This file access activity from Amazon Kendra will consume file system resources, similar to activity from your own workloads accessing the file system.

Ensure your file system is configured with sufficient resources such that your workload performance is not impacted. Specifically, if you are planning to index a large number of files, we recommend using a file system with SSD storage type, which provides higher maximum throughput and IOPS levels for requests that need to access the storage volumes.
