Hey Krishna, Can we include the perf results between the distroless/alpine/ubuntu images in the KIP?
I also noticed - Alpine employs the apk package manager, which, being relatively less popular, may pose challenges in the future. There's a potential risk that certain libraries we might need could lack support from apk Is this a concern we would have with the other images?
