Program database reads
The age old question... We have a file (or several) with a large amount of data (4.8 million records). The issue is over physical I/O vs logical I/O. One of the developers I work with thinks you can have 4 programs processing the same logical file, doing some data manipulation, and it will be just as fast as 4 program processing the same logical file all starting a unique start point and reading 1/4th of the records. I agree with him if the file is small enough to fit in memory, but, the physical file we are dealing with is 59,810,893,824 bites. Can someone help me with this??? I would like some kind of proof... Thanks, Bob
