this is a VERY strange problem. My boss have bought a new computer with two
Xeon CPUs (he loves dual machines, and we don't comlain about it ;) ).
Last wednesday I've noticed that the top command showed 4 CPU's:
[bgbg]$ top -bn1i | head
10:32am up 4 days, 1:03, 7 users, load average: 1.59,
I think it's because Xeon processors use hyperthreading, which is sort
of like a dual processor inside one processor (not really, but a bit
like it). that allows instructions from separate threads to be processed
at once by the same CPU in one cycle.
You can read more about it here:

I have even opened the box to verify the number of the CPU's.
Does anyone know anything about this behaviour? How should I treat the load
fugures I get from top?
Which kernel are you running? newer kernels (and newer CPUs)
Further to my previous posts, I have come up with more problems:
1. The instructions in the Fonts-HOWTO (specifically,this page--
http://www.tldp.org/HOWTO/Font-HOWTO/x346.html) are for an outdated
version of ttf2pt1. The line in the Perl script that reads:

Congratulations,
You just bought Intel Hyperthreading processors. Don't expect any earth breaking
performance from this (maximum 20% gain and even this is very rare)..
Thanks,

you DO have a problem with your DND records...

AFAIK, the more you run multithreaded apps, the more performance gain
you get, isn't it?
On which linux apps should one see more imporvement? I guess servers
like apache and mysql can gain a lot - relatively - from hyperthreading,
for example.

I'm using Gimp on RH8.0, and for some reason I can't seem to be able to
write hebrew in it. As far as I remember, when I used gtk 1.x, there was
no such problem - I only needed to use biditext and the correct locale.

Now, AFAIK Linux does have some scheduler code to handle this right, I
just can't seem to remember if it's in 2.4.x or only in 2.5.x

Hmmm. Then if the scheduler is unaware of SMT, then even on a
single-processor box SMT may degrade performance due to memory cache
issues -- when two unrelated threads are executed in parallel, the
effective size of the L1 and L2 caches is halved. With today's processor
vs. DRAM speed difference,
