We plan to use Keto in our projet, so I'm in discovery and testing mode. We need an API to have permissions for our UI, so I create a slim go api on top of Keto, to build JSON payload with permissions by View or Component for our micro frontend. Work nice so far. Currently I have a really simple graph with 30 tuples for testing and the response time of the Check API in Keto is between 20 to 40ms, sounds a bit slow to me, we will have a few complex checks to do. I can use goroutine to make them as fast as possible. But just to know, are this kind of response time something "normal" for Keto or not ? We use Ory Permission Language and have 4 namespaces (Tenant, Team, Product, User) so nothing really complex, A use can be part of Tenant, Team or Product, and every level use viewers, editors and owners relations to User to take permission decisions.

Hello Dominique, how are you running Ory Keto? Are you through Ory Network or are you hosting it yourself? Usually Keto is as fast as your DB allows.

I'm running it locally on local k8s cluster, connected to postgres
