We scaled #Keycloak to 2_000 logins per second and 10_000 token refreshes per seconds on #AWS and it scaled linearly in our #loadtest! It performed just fine with the latest optimizations in v26.4. What load do you run on Keycloak? Do you host your own #IAM? www.keycloak.org/2025/10/keyc...

Keycloak Performance Benchmarks: A Deep Dive into Scaling and Sizing (26.4)
Keycloak demonstrates near-linear vertical scaling, performs well in low-latency environments, and effectively offloads database usage with caching.
