SQLite数据库与其它一些数据库的性能比较
这是从一篇繁体blog中的文章：http://blog.joycode.com/fish/archive/2004/08/13/30653.aspx
MySQL(MyODBC/ByteFx), SQLite(V3), Access(2003), MSSQL(2000Sp3) 之间的效能測試
今天写了一个简单的测试程序，目的为了解自己目前所使用数据库的性能, 并希望能从中調整出更好的結果。
下面是多次测试的結果：
测试环境: Windows2003, .NET Framework 1.1, no AntiVirus, 1GB memory
测试的数据库: SQLite V3, MySQL Type=InnoDB, SQL Server 2000 Sp3, Access 20003
参数设置:
MySQL (預設*2)
max_allowed_packet=16M
key_buffer_size=16M
table_cache=128
sort_buffer_size=4M
其余选项均为預設值。
数据库的连接字符串:
Private MSSQLConnStr As String = "initial catalog=CodeLib;Connect Timeout=20;data source=(local);integrated security=SSPI;persist security info=False;"
Private MySQLODBCConnStr As String = "DRIVER={MySQL ODBC 3.51 Driver};DATABASE=CodeLib;OPTION=18475;SERVER=localhost;UID=;PASSWORD=;"
Private MySQLByteFXConnStr As String = "Database=CodeLib;Data Source=localhost;User Id=;Password="
Private OLEDBConnStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=1.mdb"
Private SQLiteConnStr As String = "Data Source=;New=True;Version=3"

00.0092(Access) < 00.0301(ByteFx) < 00.3305(SQLite) < 01.9281(MyODBC) < 03.0269(MSSQL)
从上面结果看出：
