       Informally,  total order broadcast protocols allow processes to
       send  messages with the guarantee that all processes eventually
       deliver  the  messages  in  the  same  order. In this paper, we
       investigate  the  efficiency  and  performance of a very simple
       synchronous  total order broadcast protocol, that is built atop
       a   broadcast-based   asynchronous   distributed   system.  The 
       performance  results  allow us to conclude that our Time Hybrid
       Total   Order  Broadcast  (THyTOB)  represents  an  interesting 
       trade-off  between  performance  and simplicity for total order
       broadcasts;  its  simplicity also allows its use as a benchmark
       for   total   order   broadcast  atop  Ethernet.  Finally,  the 
       experimental results that support THyTOB make a strong case for
       the  reconsideration  of  the  common  wisdom  that total order
       broadcasts  must  be always designed for the asynchronous model
       because it is the best way to guarantee safety and performance.
