So, if your problem is: tag these 10 000 emails (work, spam, personal, English, French...) it's fast? (Feed large context of mails (input) and question context).
If it's answer if this one email is spam - not so fast?
Yes, but not quite. Let me clarify.
Currently, the speedup mainly depends on the number of questions per input. The more questions for each input, the lower the average time per question, as the input is computed only once by our engine.
For tagging one email is spam or not, our engine can still be up to 3x faster, but the speedup is not as significant as with multiple questions per state.
