Currently, each pipeline run pulls large custom Windows images (~8GB) from ECR, which introduces considerable overhead and slows down builds.

Improvements that would help:

Persistent image caching across builds on Harness Cloud runners

Docker Layer Caching support for Windows containers

Option to preload frequently used custom images in Harness-managed warm pool VMs

Registry mirroring or caching to reduce pull latency

These enhancements would significantly improve pipeline performance and deliver a better developer experience.
