在 SQL Server 2000 中处理大表性能

Question

I have a table tbl_ECR_ProductData with nearly 92356143 rows. Weekly 100000 rows are imported into this table.

The table has 16 columns, 2 of those columns make up the primary key, the remaining columns are of type varchar .

My question here is when I search the table based on the remaining column values.. its taking a long time, nearly 10 mins.

How can I minimise the time? Please help me on this.. your help is appreciated... Thanks in advance! Table structure is as follows

CREATE TABLE [tbl_ECR_ProductData]( [Serial Number] [varchar](255) NOT NULL, [Act Number] [varchar](255) NULL, [Act Date] [datetime] NULL, [Act Location] [varchar](255) NOT NULL, [Manufacturer] [varchar](255) NULL, [ManufacturerPN] [varchar](255) NULL, [Act Description] [varchar](255) NULL, [Act PtNumber] [varchar](255) NULL, [Act Code] [varchar](255) NULL, [Act DateCode] [varchar](255) NULL, [Pmrl] [varchar](255) NULL, [Act ReceiveDate] [datetime] NULL, [Act Channel] [varchar](255) NULL, [Act Supplier] [varchar](255) NULL, [ImportDate] [datetime] NULL
CONSTRAINT [PK_tbl_ECR_ProductData] PRIMARY KEY CLUSTERED ( [Serial Number] ASC, [Act Location] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 90) ON [PRIMARY] )
