Description Mike Hackett 2024-08-13 21:43:02 UTC 
Description of problem:
We are seeing some increased latency with ListObjectV2 p90 of about 4.3 seconds with 200k objects in a bucket. 

My belief here is that we may be seeing listing latency due to shard count of the bucket being 4999 and only having 200k objects in the bucket as each listing operation will need to go through and check each each shard.

I would like to confirm this is the case and we are not missing anything. 

Version-Release number of selected component (if applicable):
18.2.1-229

How reproducible:
Consistent

Steps to Reproduce:
1.Create bucket with 4999 shards
2. Populate with 200k objects
3.ListObjectV2 on bucket 

Actual results:
Takes about 4 seconds 

Expected results:
Should be faster per customer
