** 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
|
||||||
|
**
|
||||||
|
** 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
