Each Put, List, Multipart operations heavily rely on making GetBucketInfo() call to verify if bucket exists or not on a regular basis. This has a large performance cost when there are tons of servers involved. We did optimize this part by vectorizing the bucket calls, however its not enough, beyond 100 nodes and this becomes fairly visible in terms of performance.
