SubjectLow bogomips on IBM x445 (kernel 2.6.5)
Hello,

I'm currently configuring an IBM x445 box with 4 Xeon CPUs (3GHz) and
hyperthreading enabled. Everything seems to work fine since kernel 2.6.5
but I keep wondering about the *very low* Bogomips numbers. Here is what
I see in /proc/cpuinfo:

processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Xeon(TM) CPU 3.00GHz
stepping : 7
cpu MHz : 2996.175
cache size : 512 KB
physical id : 0
siblings : 2
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : 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 ht tm pbe cid
bogomips : 193.53

199 bogomips seems to be pretty low for my taste, although the box seems
to work fine (and fast).

I came accross two bugs that looked very similar. However, they were
filed agains 2.4.x and should have been fixed for 2.6.x:

http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=115061

Any ideas?

Best regards,
Christoph
