Recently, there's been talk about parallel processing and sharding, which sounds quite lively, but my first reaction now isn't "how fast can it run," but rather: how does the money get out after it goes in... how does the routing work, which step is most likely to get stuck or jammed, think it through carefully first. Especially with those features like re-staking, shared security, and compounded yields, I don't think it's unfair to call them "nested dolls"; when layers keep adding, your exit strategy is often only seriously considered last. Anyway, I now prefer to earn a little less, and before trading, take a closer look at authorization, routing, slippage, and where the retreat button is. When the chain gets congested or the contract malfunctions, whether you can exit in time makes a huge difference.
