I’ve been engaged in a project for the past few months, and recently, I’ve come across a memory consumption issue. Currently, out of my total 47 GB of memory, one Weaviate instance is utilizing 13.1 GB, which seems higher than expected.

Upon consulting the Weaviate documentation, I discovered a method to calculate memory usage. The precise formula is as follows:

Number of objects \* ( (Length of single vector \* Float value precision in bytes) + (MaxConnections \* Memory used by each vector[no of connections]))

Using this formula:  
2750000 \* ((768 \* 4) + (64 \* 10)) = 9.50 GB

I would appreciate any insights into potential reasons for memory consumption beyond what this calculation suggests.

Hi! Duda from Weaviate here 🙂

This is the page where you probably got this information: [Resource Planning | Weaviate - vector database](https://weaviate.io/developers/weaviate/concepts/resources#an-example-calculation)

This is a rough estimative and it may vary with other factors, for example while indexing, it will consume more memory, or depending on some Index configurations, etc.

Also the `maxConnections` estimate doesn’t account for garbage collection.

Let me know if that helps!
