---------------------------------------
Done 1. in {{r1757389}}. With the patch, the performance is virtually
equivalent to using a regular {{FileOutputStream}} (env. 10x faster).
> [SCD] FileBackedMemoryOutputStream is 10x slower than file buffering for
> large files

> Key: SLING-5990
> URL: https://issues.apache.org/jira/browse/SLING-5990
> Project: Sling
> Issue Type: Bug
> Components: Distribution
> Affects Versions: Content Distribution 0.2.0
> Reporter: Timothee Maret
> Assignee: Timothee Maret
> Fix For: Content Distribution 0.2.0
>
>
> When doing performance test SDC agents and the following configuration, the
> distribution is ~10x slower than when using a regular file buffering method.
> The parameters are the following
> * fileThreashol = 1
> * memoryUnit = MB
> * useOffHeapMemory = false
> * tempDirectory = null
> * fileName = distrpck-create-
> * fileExtension = .default
> The size of the binary is 80MB.
> With the setup, it takes 12-14sec to replicate
> With a simple FileOutputStream mechanism, it takes around 1.4 sec to replicate
