| |
Hi all,
Anybody knows why the IO bandwidth on a NT Intel box is that much limited? Why it is that hard to get even close to 100 Mbyte/sec, if the theoretical bandwidth of PCI can be much higher? like: 66Mhz x 32bit bus = 66Mhz x4 byte = 266 Mbyte/sec?
What cause this difference between theoretical and practical bandwidth? is it CPU, chipset, or cache coherence mechanism?
Is it just the ugly Operating System? Is possible to get more on a Linux on Intel machine? On an Sgi/Irix, with THE SAME PCI bus you can easily get over 200 Mbyte/sec...
What is the best disk read bandwidth on a Linux you have ever seen? on which hardware?
Maybe the new Linux SGI file system (efs = xfs) is going to improve this, or is it a hardware limitation of Intel boxes?.....
Lot of questions here.... put in your two cents of worth, please ;)
Best regards, David, Roman.
