Recently, people keep asking me: why does on-chain data keep "lagging," even though the browser is still refreshing? To put it simply, it's often not the chain itself that's slow, but the "data pipeline" you're using that's gasping for air: the indexer/subgraph needs to process new blocks and rebuild the index first; RPCs have their own rate limiting, so when busy, it's like waiting in line for a number, and a slow response is normal. What's more annoying is when a node drops offline in the middle, and what you see is intermittent glitches.

I usually treat it as the system applying patches, small fixes: add a few more RPC nodes, cache/retry for key queries, don't take real-time performance as gospel. Recently, there's been talk about some region increasing taxes and loosening compliance, and as deposit and withdrawal expectations shift, on-chain interactions suddenly pile up, making rate limiting even more obvious... Anyway, don't immediately think of "lag" as "the chain is about to fail."
