Linkerd 2.20 Cuts Control‑Plane Memory by 85%, Enabling Leaner Mesh Deployments
Linkerd 2.20 cuts control‑plane memory usage by up to 85% while preserving mTLS, traffic splitting and observability. The shrink lets operators run the mesh on smaller clusters or free RAM for other workloads, trimming cloud spend. It also adds smarter traffic routing and rate‑limit‑aware load balancing.
