   130    130   Perhaps the two most interesting datapoints in the above table are SQLite
   131    131   and SLT.  SQLite is a long-running project with long revision chains.
   132    132   Some of the files in SQLite have been edited over a thousand times.
   133    133   Each of these edits is stored as a delta, and hence the SQLite project
   134         -gets excellent 73:1 compression.  SLT, on the other hand, consists of
          134  +gets excellent 80:1 compression.  SLT, on the other hand, consists of
   135    135   many large (megabyte-sized) SQL scripts that have one or maybe two
   136    136   edits each.  There is very little delta compression occurring and so the
   137    137   overall repository compression ratio is much lower.  Note also that
   138    138   quite a bit more bandwidth is required to clone SLT than SQLite.

   140    140   For the first nine years of its development, SQLite was versioned by CVS.
   141    141   The resulting CVS repository measured over 320MB in size.  So, the
