Thanks for this post. I had about 500.000 testresults per week and I
converted date (7), Teststation (~25) and failureCause (~100) into Symbols.
Everything worked fine and at a blazing speed because of the selection
via symbols and I had everything in Memory. I assumed that a lot of
different symbols (as compared to the 35000 ones in a 4.4 image) would
slow down the whole system.
If the next customer has higher production your post will save me a lot
of headache if I need a database then.
Cheers
Herbert
