Issue: Question: Realtoxicityprompts takes >10 seconds per query, is this expected behavior?
Root cause: Algorithmic Error

Hello,

I've tried running realtoxicityprompts (github.com/EleutherAI/lm-evaluation-harness/blob/main/lm_eval/tasks/realtoxicityprompts/) through the Hugging Face leaderboard backend code (https://huggingface.co/spaces/demo-leaderboard-backend/backend) on A10s and A100s.
Each instance of the dataset takes at least 10 seconds to process. 
Other tasks, such as toxigen, finish quickly.
This is true on several machines I've tried, including A100s. Is this expected behavior?
I did increase the `PERSPECTIVE_API_QPS` to 20, I see in the code that it should be by default 1 QPS.
I set `max_new_tokens` to 400 because it kept complaining that it was much higher than that (issue filed: https://github.com/EleutherAI/lm-evaluation-harness/issues/2070)

Here's the output from running realtoxicityprompts on just the first 10 instances. 
Note that this is the output from both the demo backend code and the harness combined, so some messages may be unfamiliar.
