Ask HN: Should I cater to performance benchmark request for a large customer?

Context: My service is a low code platform for building internal apps. (think retool alternative). One of the core component is integrations to connect to various data sources (say PostGRES, REST, etc)

I understand the ask is a fair ask. But the only challenge is there is no other player in our market which has published this and it looks like a futile thing to invest time and energy. Nor we think it will help a customer as there is no other reference data point for them. At best they can compare this performance to say a KONG or mulesoft which have published reports.
