Reasonable connection limits?

Hi,

I'm setting up FusionAuth in a multi-node cluster and am trying to determine a good connection limit for each node. If I give each node the recommended 512MB ram, how many connections could FusionAuth handle? Or is the number of connections CPU-bound? The majority of traffic will likely be to POST /api/jwt/refresh to refresh access tokens.

Thanks!

We typically see the chokepoints for FusionAuth in either the CPU (when doing a lot of password hashing) or the database.

Since usage varies, I suggest you perform your own load testing to determine connection limits. Would love to see your conclusions!
