Cosmos db in azure takes 7-10 seconds to complete

John Newsome 51 Reputation points

I'm running this code from a cosmos db in azure and it takes 7 seconds to run
await this._container.UpsertItemAsync<Heading>(header, new PartitionKey(headingId)

when I run it locally to my cosmos db emulator it takes milliseconds

the scale and indexes are set to the same. who can I speak to about this. it makes no sense and my application is running really slow because of it.

thanks in advance, John

    Hi anonymous user,

    Thanks for posting question in Microsoft Q&A and for using Azure Services.
    Sorry about the inconvenience you are facing.

    As per your question, it appears DB is taking 7-10 seconds in query execution while in Emulator it takes milliseconds.

    Could you please let us know the application in use with Cosmos DB? If using application, please try to use the latest version sdk.

    However, there are some improvements to the query caching that are available in 4.20.0 and some more bug fixes around the same in 4.26.0 and 4.3.0

    Could you please try the operations post upgrades to the above libraries and check if the performance has improved.

    Additionally, please check Network configuration or VNET Integration.

    Hope this will help. Please let us know if any further queries.
