By default, the cloud gateway 7.10.4 uses 50 threads to execute S3 MultiDelete requests, you can improve performance by increasing MaxRecursiveDeleteThreads recursiveDeleteMaxThreads to 250 in /etc/caringo/cloudgateway/gateway.cfgMaxRecursiveDeleteThreads

Warning recursiveDeleteMaxThreads can overwhelm your Elasticsearch cluster if its not sized for the workload, in some situations you may have to reduce this configuration to get less CPU load on Elasticsearch. |
recursiveDeleteMaxThreads must always be lower than threads and maxConnections
so if you set MaxRecursiveDeleteThreads recursiveDeleteMaxThreads then we recommend also changing:

Veeam v12.3 auto-provisioning of buckets feature
Veeam v12.3 introduced the concept of auto-provisioning of buckets in a single backup repository based on a configurable total objects threshold.
We do not recommend enabling this feature as it will not yield any performance improvements under Swarm. Swarm Per Domain Indexing focuses on performance improvements at the domain level not the bucket level.
Final Remarks
