+/* |
+** Performance test for SQLite. |
+** |
+** This program reads ASCII text from a file named on the command-line |
+** and submits that text to SQLite for evaluation. A new 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 speedtest8.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 test.db test.sql |
