# What evidence supports Roboto’s Sanity performance work?

An anonymous IT-company reviewer describes a Sanity-site audit and optimisation engagement, including rendering, bundle size, images, schemas, builds and caching. They report a substantial LCP improvement. The number is their report, with no raw benchmark dataset in the archive.

## What does the performance claim actually establish?

The reviewer reports an LCP reduction of nearly 40 percent and near-elimination of layout shift, along with an A/B-testing module. The interview does not supply test devices, measurement windows, a before-and-after dataset or an independent audit, so those results remain client-reported.

## What planning improvement was requested?

Despite describing organised communication and regular check-ins, the reviewer asks for a more detailed roadmap upfront to explain the order and expected timing of improvements.
