## Benefits to Cache Metadata
### Speed up meta data operations
This will greatly speed up metadata operations, such as file listing, directory traversal, check file size, read file modification time, etc. This operations usually are repeated often. Adding up all the network calls to the remote storage will slow down operations quite a lot.

Also, this will avoid API calls to the cloud storage. The price for API calls usually is not cheap.
For PUT, COPY, POST, LIST requests, they cost $0.005 per 1,000 requests on [[AWS S3|https://aws.amazon.com/s3/pricing/]].
And this is a cost which can often surprise you or your team. Some inadvertent programming logic loop changes may 10x your cost.

With SeaweedFS cacheing meta data, all requests are executed locally. The actual cost to read meta data is reduced to minimum: Just Once!

### Freedom of programmers
### Increase Productivity
Another important factor to use remote storage is that it gives your software engineers FREEDOM!
Cloud gives your scalability, but limit you on cost. Because of cost concern, your software engineers have to jump within the cost hoops.
This costs more time and effort, limits their creativity, and reduces ROI.
