I interpreted his comment as saying “where’s the 20% speed up” which seems like a more reasonable interpretation in context. A 20% speed up is actually quite substantial because that’s aggregate - it must mean there’s situations where it’s more as well as situations where it’s unchanged or worse (although unlikely to be worse under internet conditions).

The website being tested probably isn’t complicated enough to demonstrate that difference.
Even then, I remember the sales pitches all mentioning performance improvements in the order of about 10-20%
In real world conditions, not loop back synthetic benchmarks.
I believe his point is 10-20% gain is not massive.
FWIW I don't know if that is what was claimed.
20% is what real world data from Google suggested: https://www.zdnet.com/article/google-speeds-up-the-web-with-...
