Hi, You are saying that you get an "out of memory" exception. Could you tell me how large at the individual Excel files? What script and/or programming language are you using at the moment? If the individual Excel files are very large then out of memory exception can be avoided by not loading the entire file in memory but processing it gradually. Could you tell me if the Excel files are .xls (Excel 2003 and earlier) or .xlsx (Excel 2007 and later)? Low speed is usually caused by low memory available (thus it is likely a direct consequence of the way files are processed) as Windows is forced to move memory from various processes to the page file which significantly slows down the OS. Thus avoiding high memory usage should solve this as well. Which version and edition of SQL Server are you using? What query do you use to import data? I need to understand your process in order to be able to tell how to address the performance issues. Regards, Jecho

To avoid out of memory - you need to not store data in data structures but process them as a stream row by row. If you need to remove duplicates, hash function on the row would do its job (just need to store hashes in memory to find duplicates, not all the data). Very slow speed - it depends on machine, libraries and algorithms you are using.

Hi, I've read the description. To avoid the described bottlenecks I would do the following: - Since I expect it to be inserted/update operations, I would process the whole bulk of files by multiple threads, where each thread would handle one file at a time. I would optimize the number of threads depending on the architecture of the machine. This should improve the speed the files are being processed. - As for the memory limit, each Thread will only keep a certain amount (such as 100 file rows) in its memory. After this memory (or buffer) is filled up, it executes query against the database and then loads up its memory again. This way you can control, how much memory your program uses and not end up with an OutOfMemoryException being thrown. I'll write it for 500$ in C#, MS SQL. Let me know if you have any further questions, Thank you, Pavol

Dear Sir, I have more than 11 years experience of working in Microsoft Technologies; especially ASP.NET (C#, VB.NET) and SQL Server). I have experience in a variety of applications, these applications involved startups as well as maintenance of existing applications. I have recently worked on a similar kind of module, where we have a number of monthly excel sheets which are required to be imported into the DB. I would like to know, if you want to build your system as a web application or a desktop application, and whether will there be any primary/unique key in the data with the help of which we can identify duplicates. Please respond to my bid so that I can send you my resume via freelancer.com chat / message. Looking forward to hear a positive response from you soon. Best Regards, Zubair Ahmed Khan
