>    Affects Versions: Content Distribution 0.2.0
>            Reporter: Timothee Maret

> 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
