This has been reproduced in downstream (nautilus based) with more than 2k buckets and real network conditions, and basically renders RGW Bucket management unusable. Given that RGW bucket hasn't changed too much since Nautilus, this will likely be reproducible in upstream. I will try to.

Good news is that the back-end works and return the whole 2k list of buckets. Front-end reports net::ERR_INSUFFICIENT_RESOURCES, so this might be due to the front-end launching many requests in parallel for each bucket.

The problem here is that the RGW Admin OPS API does not support filters and pagination. Because of that the Dashboard RGW controller need to retrieve ALL buckets, bypass them to the UI which then does the filtering.

I created an tracker issue looooong time ago that the Admin OPS API requires that feature: https://tracker.ceph.com/issues/22168
