The on-chain data has started to "lag" again these days. At first, I thought my internet was bad... Later, I realized it's probably the indexer/subgraph/RPC chain that's a bit slow. RPC rate limiting is like a security guard at the door—suddenly, a bunch of people come to check balances and make transactions, and you get queued; subgraph isn't magic and real-time either—backend needs to fetch blocks, run mappings, write to the database, and if there's a reorganization or a node is slow, it will cause delays.

Especially during the period when new L1/L2s issued incentives to attract TVL, everyone rushed in like a swarm. Old users complaining about "mining, selling" I understand: more people = more requests = slower... The frontend looks broken, but actually it's just waiting. Anyway, now when I see data slow down, I wait for two minutes first before panicking, and I also check the raw chain or switch RPCs, to blame the project team less (though of course, they might really be poorly written).
