2 ** Performance test for SQLite.
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.
9 ** To compile this program, first compile the SQLite library separately
10 ** will full optimizations. For example:
12 ** gcc -c -O6 -DSQLITE_THREADSAFE=0 sqlite3.c
14 ** Then link against this program. But to do optimize this program
15 ** because that defeats the hi-res timer.
17 ** gcc speedtest8.c sqlite3.o -ldl -I../src
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:
22 ** ./a.out test.db test.sql
34 #include <sys/times.h>
41 ** hwtime.h contains inline assembler code for implementing
42 ** high-performance timing routines.
