MS SQL Server autogrow configuration with heavy loaded database I have a database its size around 200G and it is heavy loaded with many inserts happens every day (it is grow around 3 to 4 GB every day), but the Auto-Grow setting is set to 1 MB.

I think this is a problem and I think if I set it to 1GB it will increase the performance and capability, is that right?

I think with 1MB auto-grow the database will be always busy to allocate a new space, is that right ?
Any suggestion for best practical way to increase the performance?

Thanks all
1 MB is not the right choice for autogrowth !

You should always set auto growth to a sensible value that suits your environment. I tend to capture the autgrowth value for a month and then average it out to give me a ball park figure of autogrowth for my database .

I have provided a sample script here as well. Also refer to Mike Walsh's answer.

The default trace keeps track of AUTOGROWTH events out-of-the box. Below script will give you a good starting point.

Also, Instant file initialization is a boon when auto growth kicks in (ONLY applies to data files).

IF OBJECT_ID('tempdb..#autogrowthTotal') IS NOT NULL
    DROP TABLE #autogrowthTotal;
IF OBJECT_ID('tempdb..#autogrowthTotal_Final') IS NOT NULL
    DROP TABLE #autogrowthTotal_Final;

DECLARE @filename NVARCHAR(1000);
DECLARE @bc INT;
DECLARE @ec INT;
DECLARE @bfn VARCHAR(1000);
DECLARE @efn VARCHAR(10);

-- Get the name of the current default trace
SELECT @filename = CAST(value AS NVARCHAR(1000))
FROM ::fn_trace_getinfo(DEFAULT)
WHERE traceid = 1 AND property = 2;

-- rip apart file name into pieces
SET @filename = REVERSE(@filename);
SET @bc = CHARINDEX('.',@filename);
SET @ec = CHARINDEX('_',@filename)+1;
SET @efn = REVERSE(SUBSTRING(@filename,1,@bc));
SET @bfn = REVERSE(SUBSTRING(@filename,@ec,LEN(@filename)));

-- set filename without rollover number
SET @filename = @bfn + @efn

-- process all trace files
