Low bogomips on IBM x445 (kernel 2.6.5)

[Christoph Pohl]

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

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
