No, a reason why the partition with Linux (ReiserFS or Ext3) is always slower
than the Windows partition?

Yeah the HT is enabled but as I said that changes nothing on the result, if I
enable or diable it on the desktop machine.
Sorry about the I/O, I explained something wrong. Look below, I answered Paulo
Marques to explain everything.

I hope you are talking about a hardware/kernel problem and not a software
problem, because I tried it also with LiveCD's and they showed the same results
on this machine.
I'm not a linux expert, that means I've never done anything like that before,
so it would be nice if you give me a hint what you see in this results. :)

These are just snips of billions of lines...
The crazy things is, that the read operation takes only 0.000022 on the
notebook and 0.000138 on the desktop, also there are a LOT more _llseek
operations between each read operation (to much to list them) on the desktop
but one possible reason is that I didn't catch the same area of processing
lines... (it scrolls much too fast)

I haven't said that there is any data loaded from files DURING the operation
(sorry for this). Random access files are used, but not for this process. What
I do is building up a r-tree index structure to get faster access to the stored
data, but everything is currently done completely in memory.

w/o "mem=768M":
---------------
$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
reg01: base=0xc0000000 (3072MB), size= 256MB: write-combining, count=1
reg02: base=0xe0000000 (3584MB), size= 256MB: write-combining, count=1
$ cat /proc/meminfo | grep MemTotal
MemTotal: 1033620 kB
with "mem=768M":
----------------
$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
reg01: base=0xc0000000 (3072MB), size= 256MB: write-combining, count=1
reg02: base=0xe0000000 (3584MB), size= 256MB: write-combining, count=1
$ cat /proc/meminfo | grep MemTotal
MemTotal: 775116 kB
The speed didn't get any better through this change.
Just for information, here my kernel options for memory size...
