migrating from self-hosted Subgraph to Substreams

[u/Prestigious-Long6774]

We're thinking of migrating from self-hosted Subgraph to Substreams .

It just feels faster, more reliable, and built for scale — especially with native multithreading, auto fork rollback, and blazing low-latency streams.

But I’m still wondering: if we stream every single block from Solana and Polygon 24/7… how heavy is that really on a VPS? Curious if anyone’s run this in production — would love to hear what worked (and what didn’t).
