profiling timings in next-on-pages (CF workers)

we've been adopting next-on-pages recently and it's been working really, really great (kudos to Dario/James/any other contributors I might be missing!)

(on a somewhat similar note to the messages above) I did want to know if either of you had any methods to reliably profile timings in Cloudflare workers – we were surprised to see that:

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

const t0 = Date.now();
const data = env.KV.get(key);
const t1 = Date.now();

seemed to be reporting

XXX ms

XXX ms

in lab conditions even on cache hits (where in a plain worker we see

XX ms

XX ms

_. Then we realized it wasn't KV but rather the first IO we had (and with the CF Workers security measures, we understand we could be measuring things before that I/O that just wait for the I/O to tick?)
