  It seems to be comparable.  I did a simple comparison vs. the Weblogic
driver quite a while ago.  I just execute a single SELECT statement, then
fetched about 20,000 rows.  FreeTDS was faster than the Weblogic driver at
that time.

  I believe so.  I believe that TDS only allows one query in-progress per
connection.  Some other JDBC drivers seem play tricks to avoid this.
