(having no clue about lmbench) I take this exercise to roughly compare. Running the original 2.4.21-pa9 here are times: Tue Aug 12 09:59:55 CEST 2003 [...] # Build kernel: 19'58" Tue Aug 12 10:19:53 CEST 2003 [...] # Build modules: 7'46" Tue Aug 12 10:27:39 CEST 2003 Running this new kernel: Tue Aug 12 12:28:37 CEST 2003 [...] # Build kernel: 20'8" Tue Aug 12 12:48:45 CEST 2003 [...] # Build modules: 7'47" Tue Aug 12 12:56:32 CEST 2003 The difference are so small that a more accurate tools would be requested. hth anyway, Joel ------------------------------------------------------ Soldes Tiscali ADSL : 27,50 euros/mois jusque fin 2003.
