DeclarativeResponse is slower than encrypted cached gzip !?

[Mupli]

As in title .. I tried to improve some of the requests but no luck here.
On my test with autocannon I have sent encrypted data via DeclarativeResponse - the time/performance was much worse than sending the same data with function and (res...end(data)).

version that I'm using : 20.51.0

Other issue is that DecalrativeResponse is missing in ESM declaration file.
