 ## Performance considerations
 
-A reindex job can be quite performance intensive. The FHIR service offers throttling controls to help manage how a reindex job runs on your database.

-> It is not uncommon on large datasets for a reindex job to run for days.

-Below is a table outlining the available parameters, defaults, and recommended ranges for controlling reindex job compute resources. You can use these parameters to either speed up the process (use more compute) or slow down the process (use less compute).

-| `QueryDelayIntervalInMilliseconds`  | The delay between each batch of resources being kicked off during the reindex job. A smaller number speeds up the job while a larger number slows it down. | 500 MS (.5 seconds) | 50 to 500000 |
-| `MaximumResourcesPerQuery`  | The maximum number of resources included in the batch to be reindexed.  | 100 | 1-5000 |
-| `MaximumConcurrency`  | The number of batches done at a time.  | 1 | 1-10 |

+A reindex job can be quite performance intensive. The FHIR service offers throttling controls to help manage how a reindex job runs on your database. You can use `MaximumResourcesPerQuery` parameter to either speed up the process (use more compute) or slow down the process (use less compute). `MaximumResourcesPerQuery` parameter allows to set the maximum number of resources included in the batch to be reindexed. The default value is 100 and you can set value between 1-5000.
