Az async – await dolgokkal fel lehet szabad\u00edtani pl. as ASP.NET \u00e1ltal is haszn\u00e1lt ThreadPool sz\u00e1lakat, hogy m\u00edg egy hossz\u00fa ideig tart\u00f3 nem CPU hanem IO intenz\u00edv folyamat fut, addig legyen szabad sz\u00e1l kiszolg\u00e1lni a rendes, kicsi, gyors k\u00e9r\u00e9seket.<\/p>\n

De ha \u00fagy aszinkron\u00edtunk egy blokkol\u00f3, IO intenz\u00edv k\u00e9r\u00e9st, hogy becsomagoljuk Task.Run-ba, akkor adtunk a sznak egy pofont, mert pont ugyanabb\u00f3l a ThreadPoolb\u00f3l vett\u00fcnk el sz\u00e1lat, mint amit az ASP.NET is haszn\u00e1l (felt\u00e9telezve az alap TaskSchedulert haszn\u00e1ljuk).
