   2 ** Performance test for SQLite.
   3 **
   4 ** This program reads ASCII text from a file named on the command-line
   5 ** and submits that text  to SQLite for evaluation.  A new database
   6 ** is created at the beginning of the program.  All statements are
   7 ** timed using the high-resolution timer built into Intel-class processors.
   8 **
   9 ** To compile this program, first compile the SQLite library separately
  10 ** will full optimizations.  For example:
  11 **
  12 **     gcc -c -O6 -DSQLITE_THREADSAFE=0 sqlite3.c
  13 **
  14 ** Then link against this program.  But to do optimize this program
  15 ** because that defeats the hi-res timer.
  16 **
  17 **     gcc speedtest8.c sqlite3.o -ldl -I../src
  18 **
  19 ** Then run this program with a single argument which is the name of
  20 ** a file containing SQL script that you want to test:
  21 **
  22 **     ./a.out test.db  test.sql
