Hi. It seems to me (From the limited knowledge that I have!) that my machine is not hyperthreading. I have done the following. 1. Ensured that the capability is enabled in the BIOS. 2. FreeBSD recongizes the capaiblity CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (1866.74-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf29 Stepping = 9 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> Features2=0x4400<CNTX-ID,<b14>> Logical CPUs per core: 2 real memory = 1073676288 (1023 MB) avail memory = 1033097216 (985 MB) ACPI APIC Table: <IntelR AWRDACPI> FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 3. The kernel is built for SMP # SMP -- Generic kernel configuration file for FreeBSD/i386 SMP # Use this for multi-processor machines # # $FreeBSD: src/sys/i386/conf/SMP,v 1.5.6.1 2005/09/18 03:37:58 scottl Exp $ include GENERIC1 ident SMP-CUSTOM # To make an SMP kernel, the next line is needed options SMP # Symmetric MultiProcessor Kernel device atapicam 4. In the past top would show the 2 different logical CPUs working however, this is not the case anymore. Can anyone help we with this issue. I am using 6.2 release. Thanks in advance. Derrick
