Yees, possibly true in normal case... but there is something wrong... I feel
that the question is not about 25% here...

If I have tried the 32-64k settings with NT (it's more simple to change
these setting there dynamicaly), the speed went down to something similar
than I had with the Linux workstation, less then 100k/sec... However,
reducing the chunk size changed only the write performance, not the
reading... It's not too clear for me...
