The archive rate is only around 60mb/s on a large cluster (72 warm nodes). How to improve the rate to around 100mb/s?

What I have tried:

1. Enable the S3-accelerate mode. However, ES doesn't support it per [Enabling Transfer acceleration · Issue #64831 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/64831)

2. It doesn't help to adjust `max_snapshot_bytes_per_sec` since the default limit 40mb/s is sufficient.
