    since I'm not so expert, please clarify the BIT vs BYTE issue. Of 
course there is an 8 factor between them, which is not far from a 10 
factor, and can change numbers completely. When speaking of bandwidth 
the numbers are usually expressed in mega bits per second (Mbps) and 
lower-case 'b' means bits. Upper-case 'B' means 'bytes'. I get confused 
when you speak of  "4Gb" of memory. You meant "GB", didn't you? I wonder 
if in other places you meant 'B' for bytes but wrote 'b'. Please clarify.

    Thanks for your tests, which are interesting for us as well
