Doubt(load large amount of data) -reg
I assume that you mean a file sie of 566MB? Is this the size of the text file? If so how is the text file structured? What type of system are you running? How much physical memory do you have? What kind of processing do you want to do with the data? Do you have to have all of it at once? For example, if this is a text file with numeric data (assume 7 digits per value), then you would need about 566MB to store a single copy of the object. If you want to process it, I would suggest at least 4X your largest object in physical memory. You could also consider using a data base to store and access the data. You need to provide a little more information to get a suggestion.
