[ceph-users] [S3] Scale/tuning strategy for RGW in high load

Hi, I'm using Ceph v18.2.4, non-cephadm. Over time, my RGW cluster receives more requests, and when it reaches a certain threshold, I will manually scale more Radosgw instances to handle the increased traffic. - Is this a normal practice? - Are there any tunings I can do with RGW to make it handle more requests per instance? - Also, I'd like to know if there is any way to auto-scale those RGW instances (in a non-cephadm cluster)? Thanks
