In every published test I have seen EGTB files are a wash (no win/no loss) and bitbase files are a win. However, if you have a fast, striped Ultra320 SCSI array with 15K RPM disks, then I think EGTB will be of much more benefit. Nobody has such a system to test, or [at least] nobody has published the results on such a system. On some mediocre IDE drives, I expect that the cost of the lookup has about the same value as the knowledge gained.
