In total we have now: -FreeBSD 4 PIC (no asm part) -FreeBSD 7 APIC -FreeBSD 7 PIC -FreeBSD 7 PREE APIC -FreeBSD 7 APIC JHB Some quick comments: -PIC is much slower in masking interrupt (7k in PIC vs 3k in APIC) -PREE let new thread save less than 500 ticks of 'queue' while preempted threads are often resumed after a lot -JHB patch shaved 2.5k ticks in interrupt masking op For graphs, data and more comments: http://mercurio.sm.dsi.unimi.it/~pisati/interrupt/ bye -- Paolo "le influenze esterne sono troppe, il mondo reale non e' mica quello fatato dei komunisti :-p" - Anonymous Lumbard
