Experimental evaluation on a real system shows that the proposal achieves an average speedup by 5% with respect to Linux.This work was supported by the Spanish Ministerio de Economía y Competitividad (MINECO) and Plan E funds, under Grant TIN2012-38341-C04-01, and by the Intel Early Career Faculty Honor Program Award.Feliu-Pérez, J.; Sahuquillo Borrás, J.; Petit Martí, SV.; Duato Marín, JF.
