There is no defined maximum size for datagroups so capacity is actually only limited to system resources. On newer platforms it's possible to store up to a few million records. As for performance, the lookup values are hashed and stored in memory, so searching is reasonably fast. If you want exact numbers, your best bet is probably to set up timing and look at it under test.
