Lately, I keep encountering those moments when the "data stalls," even though the blockchain has clearly produced a block, but the wallet/frontend seems a bit slow. Thinking about it later, it's mostly not the chain itself, but the intermediate layers: the indexer needs to fetch logs and organize them, Subgraph has to run mappings and write to the database, and delays happen during reorganizations or backlog; plus, with RPC rate limiting, especially when everyone is checking balances or spamming transactions, getting a 429 error causes retries, making it look like intermittent issues.

A couple of days ago, before and after the upgrade of that mainstream public chain, people in the group were speculating whether projects would migrate. I think we shouldn't rush to conclusions; the upgrade window is the easiest time to expose bottlenecks in these "middle layers," and a feeling of lag doesn't necessarily mean the protocol has issues. Anyway, I now compare data from two sources simultaneously; I prefer confirming more slowly rather than letting temporary lag sway my emotions.
