V8 might have changed how it behaves with --perf-basic-prof.
Example:
importfsfrom'node:fs'// File with URLsconstcontents=fs.readFileSync('./out-positive.txt','utf8').split('\n').filter(l=>l.length>3)letresult=0// warmupfor(letcontentofcontents){result=newURL(content).toString().length}process._rawDebug('benchmark starts')for(letcontentofcontents){result=newURL(content).toString().length}
If someone else wants to investigate it before me, use the out-positive.txt.
Note: you can't compare the result with Node.js <= v18 because URL has changed in v19. You should compare it against other profilers (pprof, CDT, Apple Instrument, linux_perf)
