Cognite Function single call runtime

Hi community,

I have noticed a large discrepancy in runtime when running my handle function as a single Cognite Function call and when I run the handle function locally. And yes, this is the runtime of the actual CALL, not the creation/deployment of the Cognite Function. The handle function is doing some calculations on a time series with around 500 000 datapoints. Locally, it runs under 1 minute, while through Cognite Function call it takes around 9 minutes. 

Do you have any idea what could cause the large discrepancy?

Thanks!
