No faktycznie - chyba byłem zmęczony jak to przeglądałem. Jest w kilku miejscach i to około 120MB nawet !. No tak, to następna granica 150 .. albo 200 .

martwi mnie to 1038 bo wydaje mi się że miałem ok 2000 a potem nalge spadło.. od czego to zależy (ram i procek nie zmieniany p IV 631 i 2x512MB ddr2), być może tylko mi się wydaje ale chyba coś jest nie tak.

(just wanted to post for reference, I actually (unfortunately) don't speak polish  , if you want we can outsource this in the kernel & hardware subforum) |
Could You tell me how is it possible, You get so big transfer rate when cached read?
I have SATA/320 controller and SATA/320 disk... It's just up to 800MB/s
What does it depend on?
Thanks!
Btw: Are You the KernelOfTruth from #reactos @ freenode?
Mam nadzieje ze nikt sie nie obrazi za odrobinke angielskiego na polskim forum?

as far as I understand it depends on a lot of components how high your cached read rates are:
- connections between north- & southbridge
- connection to ram
- to processor
- harddrive
=> so all in all the whole "infrastructure" of your computer
so this should indicate how high your theoretical maximal achievable throughput would be
what mainboard do you have?
for me it's a P5W DH Deluxe & Corsair 6400 DDR2 Ram (@800 MHz), 2 GB, Conroe 6600 so perhaps those components might be the difference
is your controller connected via pci or pci-express?

I don't understand this fully, but as far as I understand you're wondering why I'm posting under a polish forum while I only speak english
I was searching for some hdparm tweaks / settings and stumbled over this thread

I have Athlon64 3000+ Venice @ FSB: 280MHz x9 = 2528MHz connected to Gigabyte K8NXP-9 (S939) with 1GB RAM DDR400 CL2.5 DualChannel
Maybe You are right...
I was just wondering why i have 800MHz if nForce4 Ultra which i have supports HT 1000MHz ;]
but never mind... forget it
The last sentence i have written was directed to other polish users. I asked them if it is anything wrong we are talking English, in Polish section
Hmm...
That's very interesting 'cos I saw a man with the same nick on also on #gentoo and #gentoo-xeffects...
It this nick is registered i don't think there are 2 people with the same nickname
Soo? What's the truth?
