I'm planning to update the system to 7.0 and want to ask about the enabeling or disablening of hyper threading in BIOS. What I've seen on my current system is that when I enable hyper threading my cpu-graph only shows up to 50% in gkrelm and xfce's cpu graph. Should I compile the kernel with special parameters or is it just the inability of gkrelm and xfce's cpu graph to detect hyper threading I'm seeing? ------------------------- WARNING: MPSAFE network stack disabled, expect reduced performance. acpi_alloc_wakeup_handler: can't alloc wake memory ACPI APIC Table: Timecounter "i8254" frequency 1193182 Hz quality 0 CPU: Intel(R) Pentium(R) 4 CPU 3.40GHz (3412.10-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf34 Stepping = 4 Features=0xbfebfbff Features2=0x441d> Logical CPUs per core: 2 real memory = 1073414144 (1023 MB) avail memory = 1028616192 (980 MB) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 ioapic0 irqs 0-23 on motherboard -------------------------------- Thanks /Leslie
