Doc Type: Enhancement
Doc Text:
.Ceph Object Gateway’s default shard requests on bucket index, `rgw_bucket_index_max_aio`, increased to 128 Previously, outstanding shard requests on a bucket index was limited to 8 causing slow performance with listing buckets. With this release, the default number of shard requests on a bucket index, `rgw_bucket_index_max_aio`, has been increased from 8 to 128, thereby improving the bucket listing performance.

Description Casey Bodley 2020-08-25 19:31:45 UTC 
Description of problem:

The maximum of 8 outstanding shard requests on a bucket index is an unnecessary bottleneck, especially for bucket listing which already has issues scaling to larger shard counts. the Objecter's inflight ops throttle is already preventing us from flooding the osds with requests
