Lo que me parece aun mas triste de todo esto es que un Core 2 Duo no alcanza para correr una VM de JavaScript simple lo suficientemente rapido como para lograr el modestisimo logro de correr UIs relativamente poco exigentes, y que haga falta poner un JIT para lograr simplemente eso...
O bien el estado de la VM anterior era calamitoso, o como programamos hoy en dia es un desastre, o las dos. Andres.
