Historical Azure SDK discovery benchmark

The SDK-backed AKS cluster picker belonged to the retired interactive Lift workflow. Chat and quickstart --azure-discovery are removed; these measurements are historical, not an available discovery alternative or a current qualification. Standalone kmx aks up/down and host inference discovery through the Azure CLI remain independent.

The archived implementation and reproduction instructions describe the former credential chain, paging and client reuse. Its live benchmark and SDK-only tests are no longer in this checkout.

Historical measurements

Measured against the active Azure subscription on 2026-09-16, listing 19 AKS clusters. Requests alternated CLI and SDK sequentially. All runs returned the same set of resource-group/cluster identities. The SDK was not primed before the first run.

Run	CLI	SDK
First	13.179 s	3.506 s
Repeat 1	11.212 s	2.384 s
Repeat 2	11.257 s	2.357 s

A separate fresh SDK credential/client took 3.435 s. In this small sample, first-call listing was about 3.8× faster and repeated listing about 4.7× faster, saving approximately 9 seconds per cluster-list step. Timing included credential resolution and all response pages, but excluded executable compilation and the subscription picker. CLI and SDK could use different ARM API versions; service/network variability applies. No cloud resources were changed.
