1.1 misho 1: /*
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
