    keyword=Intel CPU network speed and max data rate

    I got the blaster program for the intel CPU from Bryan
    /adaqfs/home/adaq/Blast/Blast 
    
    with a 10000 bytes event size I got 83 Mb/s transfer rate to adaq1
    
    With fake data in the ROC, I reached the maximal speed that Bryan
    mentioned he got with FADC about 113 MB/s. 
    
    With one ARS board, I get only 71 MB/s, the board speed is the limiting
    factor there.
    
    With fake data, we manage to record everything on adaq1 so far with some
    fluctuations that I will have to study but it seems most of the time we
    can record up 100 Mb/s.
    
    I will setup a second crate and try with two crates to see if this is
    maximum data rate we can put on disk.
