What is the issue or error you’re encountering

Hyperdrive is slow

What steps have you taken to resolve the issue?

Connected to the database without Hypderdrive. Latency was improved a lot

What are the steps to reproduce the issue?

Database: Postgres in ap-northeast-1 region of AWS (Supabase)
Connected from: Cloudflare Workers

In Cloudflare dashboard, the hyperdrive metrics page says the median latency is 200ms or so, but on Workers side it’s about 600ms.
If I don’t use Hyperdrive and connect to the database directly, the latency is improved a lot.

Does anyone know why?
