# Fast Mode

Fast mode is a way to further reduce test execution time by aggressively deduplicating recorded requests. Our deduplication algorithm compares the schema of request, response and outbound calls of requests and only retaining one of the entire group of requests that have the same schema.&#x20;

Fast mode takes it one step further aggregating requests based on schema of the request & its response, thereby, ignoring the outbound call's schemas.&#x20;

This will will replay only a fraction of requests that we have recorded.

To enable Express Mode:-

1. Go to your *.htTestConf.js*
2. Enable *fastMode: true,*

Please note that Express mode is enabled by default for a user.
