Hello, I have a machine with an Intel p4 3.2ghz FSB800 w/ 1MB L2 cache and I wanted to know your opinion about some kernel options that would boost the performance of this kind of processor. Timecounter "i8254" frequency 1193182 Hz quality 0 CPU: Intel(R) Pentium(R) 4 CPU 3.20GHz (3206.95-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf34 Stepping = 4 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Hyperthreading: 2 logical CPUs real memory = 2146369536 (2046 MB) avail memory = 2079641600 (1983 MB) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 ioapic0: Changing APIC ID to 2 ioapic0 <Version 2.0> irqs 0-23 on motherboard Pentium Pro MTRR support enabled Will the GENERIC options fit for this or will other options boost this processor to his maxium? I remember in 4.x that HT was an option but now it's seems defaulted. Thanks for your time. Regards.
