> Jetty's SSL Engine implementation creates a great amount of garbage for GC.
> This is because when SSLEngine encodes/decodes any byte[] of input data, it
> *creates an entirely new* byte[] as output and *does not reuse* it.
> !HDDS-10364.png|width=717,height=271!
> This means for every MB of data flows through S3G, there's 1 MB of garbage
> for S3G GC to clean up. The cost of GC is linear to the data throughput.
> When I do a comparison of writing data from S3 with ratis-streaming vs S3
> with normal async API, ratis-streaming
