At the top of the page where you add a taxonomy queue (the Smart Queue Taxonomy module needs to be enabled for this), there's the following:
(...) Using this with large or too many taxonomies may degrade performance.
What (number) is meant by 'large' or 'too many'? Did people experience problems with this? If so, at how many vocabularies/terms?

merlinofchaos CreditAttribution: merlinofchaos commentedFor a single vocabulary, I don't think the size matters much.
If you select multiple vocabularies, it has to process all of the possible combinations of terms, so thousands of terms could start to have a performance impact on your site. I would recommend not doing this.
I didn't do any benchmarks so I don't have specific numbers; I threw in the warning because, at the time I wrote it, it seemed like a good idea to let people know that doing something like combining two taxonomies each with a thousand terms (which leads to a million unique combinations) could really create lots of subqueue data.
