-** Performance test for SQLite.
-**
-** This program reads ASCII text from a file named on the command-line.
-** It converts each SQL statement into UTF16 and submits it to SQLite
-** for evaluation.  A new UTF16 database is created at the beginning of
-** the program.  All statements are timed using the high-resolution timer
-** built into Intel-class processors.
-**
-** To compile this program, first compile the SQLite library separately
-** will full optimizations.  For example:
-**
-**     gcc -c -O6 -DSQLITE_THREADSAFE=0 sqlite3.c
-**
-** Then link against this program.  But to do optimize this program
-** because that defeats the hi-res timer.
-**
-**     gcc speedtest16.c sqlite3.o -ldl -I../src
-**
-** Then run this program with a single argument which is the name of
-** a file containing SQL script that you want to test:
-**
-**     ./a.out database.db test.sql
