Is there any stable Ethereum Light Client? Which one is production ready? What's the status and the roadmap? Moreover, I'm looking for some metrics related to a Light Client:
- Runtime resources usage (memory, cpu)
- How much time it takes to sync (from genesis) on a mid level-mobile device (let's say we have max 300MB RAM available)?
- How much time it takes to re-sync after 1 week break?
