If you need any performance at all I HIGHLY recommend you get an experienced
consultant in to help provision/configure your system.

Mike,
The transaction log entries are crucial to peak performance when it comes to
writes. Essentially if one insert is held up due to bottlenecks on writing
to the log file so will all other transactions that will also be writing at
that time. The more concurrent writes you have the more the potential for a

OK. Here is declaration of OpenSqlFilestream:

function OpenSqlFilestream(
Path: PChar;
Access: Cardinal;

txnToken: TtxnToken;

In SQL 2008, you can INSERT into an existing table, using a nested SELECT,
with the same performance as SELECT INTO (in many cases). So you can create
the table on your preferred filegroup, and then copy the rows from the other
table into it. Check the BOL for full details.

I suspect this is a "how do I do this in Delphi", which is not easy to
assist with, since I don't know Delphi. I would guess that you have some
error around one of the parameters to OpenSqlFilestream or the
import of it.
Could you post the code, including how you import OpenSqlFilestream?
No promises, but maybe we are able to spot something.

More or less. BULK INSERT uses OLE DB, and below the covers there are
is a command INSERT BULK, which you can see in a Profiler trace.
But keep in mind that while they are similar, they are to some extent
different implementations, and there are subtle differences. Sometimes
BCP accepts a file that BULK INSERT barfs at, or vice versa.

SELECT...INTO creates the table on the default filegroup. You'll need to
mark the secondary filegroup as the default one beforehand:
ALTER DATABASE MyDatabase
MODIFY FILEGROUP [MySecondaryGroup] DEFAULT;

Thanks. I am aware of this but was just speculating that "SqlBulkCopy" is
probably a wrapper for BULK INSERT or some other high-volume (native) SQL
Server statement (possibly internal to MSFT only). My original issue however
is whether running "SqlBulkCopy" (or BULK INSERT directly) will have an

Re: Transaction load

BULK INSERT is a Transact-SQL statement whereas the SqlBulkCopy class (and
its unmanaged ODBC/OLEDB cousins) are native client APIs. Unlike BULK
INSERT, the client APIs allow you to load directly from program variables.

Thanks. Can you also briefly elaborate on my last response to him (just
posted). Appreciate your help.
Not familir with this but probably not necessary for my needs unless it
solves some problem specificically related to this issue (resource
exhaustion). The bulk insert I tested ("SqlBulkCopy" in .NET) is very fast

Thanks for you help and I agree. It's hard to appreciate when you're not
really familiar with the details. In this case however it's a fairly simple
situation. Assuming 10,000 customers in the short-term, 100,000 long term,
and each customer will be uploading a single file just once every few weeks

Re: Transaction load

2009-11-08T12:09:16Z

Thanks. I'm actually using the "SqlBulkCopy" class (assuming you're familiar
with .NET) and this presumably wraps BULK INSERT (still researching things).
I also took a quick look at ROWS_PER_BATCH and this may prove useful (thanks
for pointing this out). If possible however, I'd like to insert all data in

Hi
As Andrew said to separate LOG and DATA files must be e first step
Have you considered using SSIS Package to insert the data from the files ,
it hs very nice feature named 'fast load'
