These optimizations are difficult to implement, frequently error-prone, and lead to inconsistent behavior across runtimes. Bun's "Direct Streams" optimization takes a deliberately and observably non-standard approach, bypassing much of the spec's machinery entirely. Cloudflare Workers' IdentityTransformStream provides a fast-path for pass-through transforms but is Workers-specific and implements behaviors that are not standard for a TransformStream. Each runtime has its own set of tricks and the natural tendency is toward non-standard solutions, because that's often the only way to make things fast.
在能力的提升、生态的健全、资源的投入影响下，各行各业正在尝试把智能体真正的用起来。根据麦肯锡2025年全球调研显示，约62%的受访组织已在部分业务中尝试智能体（23%为至少一个场景的规模化部署，39%为试验性应用）；但从业务职能的具体采用数据来看，产业对智能体的应用还处于早期阶段：根据该调查，对于智能体应用最多的职能依次是IT、知识管理、营销和服务，以应用最多的IT为例，仅有2%和8%的受访企业IT部门全面规模化（Fully Scaled）和规模化（Scaling）的应用智能体，以及6%和7%的企业IT部门试点(Piloting)和试验(Experimenting)的应用。
