   While it might not exactly be an achievement of this particular team, nodejs/node#48078 might still be worth mentioning during the announcements since it might be one of the most impactful performance improvements in a long time (thanks to @santigimeno and @bnoordhuis).

   Thanks for the mention but I would rephrase this a bit.

   Thanks to @bnoordhuis and @isc-projects which iiuc sponsored some of his work.

   I'd like to mention that startup has gotten a good bit faster in the most recent release (v20.1.0 -> v20.2.0), as a result of nodejs/node#47055+nodejs/node#47144+nodejs/node#47958:

                                                                                        confidence improvement accuracy (*)   (**)  (***)
   misc/startup.js count=30 mode='process' script='benchmark/fixtures/require-builtins'        ***     23.94 %       ±0.64% ±0.88% ±1.20%
   misc/startup.js count=30 mode='process' script='test/fixtures/semicolon'                    ***     17.58 %       ±0.43% ±0.61% ±0.85%
   misc/startup.js count=30 mode='worker' script='benchmark/fixtures/require-builtins'         ***     28.64 %       ±0.47% ±0.66% ±0.91%
   misc/startup.js count=30 mode='worker' script='test/fixtures/semicolon'                     ***     24.70 %       ±0.88% ±1.25% ±1.81%
   
   Be aware that when doing many comparisons the risk of a false-positive result increases.
   In this case, there are 4 comparisons, you can thus expect the following amount of false-positive results:
     0.20 false positives, when considering a   5% risk acceptance (*, **, ***),
     0.04 false positives, when considering a   1% risk acceptance (**, ***),
     0.00 false positives, when considering a 0.1% risk acceptance (***)
   

   I am working on some further improvements too.
