Slow Razuna API



we have a single server installation of Razuna and we are using it for the image/document repository for our webstore. The problem is that now that we have a lot of assets Razuna API became very slow.

I would like to ask you what can we do to speed up the Razuna API? Are there any cluster deployments possible or maybe there is a way to separate some of the Razuna functionalities across multiple servers?

Thank you!

Best wishes
