Processing power to rate limit 100k IPs per day across 1.5M requests per day

The job I work at has a process heavy application that they want to rate limit per user. I'm trying to determine the processing power required to run a NodeJS rate limiter on 100k requesting IPs across 1.5M requests peaking at 60req/s per day. I was thinking to use https://www.npmjs.com/package/rate-limiter-flexible and hold it in memory. I have no idea how I would predict this without manually creating it.
