<P align=left>The following are benchmarks that we have performed
with DBISAM and various competing database engines. These benchmarks
are strictly SQL-based and use only SQL SELECT queries using SQL-92
syntax, except where noted. All resultant timings are in milliseconds
and all queries were executed with a request for a live result
set, if possible.</P>
