# About the Push API Processing Delay
When you use the Push API to add or update one or several [items](https://docs.coveo.com/en/210/) in a Push [source](https://docs.coveo.com/en/246/), the service normally returns a `202 Accepted` response almost instantaneously.
This merely means that the items were successfully forwarded to the Push API queue;
it does _not_ imply that the items were successfully processed and indexed.

Typically, you must wait between 2 and 5 minutes before your newly pushed items begin appearing in your [index](https://docs.coveo.com/en/204/).
You can't directly alter or reduce this delay, as it's the sum of the smaller delays which are incurred while the items are transiting through the different stages of the [Coveo indexing pipeline](https://docs.coveo.com/en/184/).

The infrastructure automatically scales depending on load variations to maintain the lowest possible processing delays.
Moreover, the Coveo team constantly monitors those delays and regularly fine-tunes the infrastructure scaling mechanisms.

The total Push API processing delay may vary depending on a number of factor such as:

* The number and size of items to process.
* The current load on the Push API queue (which is multi-tenant).
* The current load on the [document processing manager (DPM)](https://docs.coveo.com/en/191/) queue (which is multi-tenant).
* The index commit frequency (typically every minute, although the index commits immediately when its queue reaches a certain threshold).
* Coveo infrastructure scaling delays (for example, it can take a few seconds to provision an AWS Lambda function container).

You can review your Push API usage, as well as the number of items in your index, on the [**System Performance**](https://platform.cloud.coveo.com/admin/#/orgid/organization/system-performance/) ([platform-ca](https://platform-ca.cloud.coveo.com/admin/#/orgid/organization/system-performance/) | [platform-eu](https://platform-eu.cloud.coveo.com/admin/#/orgid/organization/system-performance/) | [platform-au](https://platform-au.cloud.coveo.com/admin/#/orgid/organization/system-performance/)) page in the [Coveo Administration Console](https://docs.coveo.com/en/183/).
