Ok, I coudl use mysql, but think we have around 15M entries and I would have to add to each a file from 1KB to 150KB, in total the files size can be around 200GB. How will be the performance of this in mysql? _________________________________________________________________ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE
