Thanks !

Performance enhancements

Added experimental support for direct data movers communication when both are running on the same server (for example, when backing up to a local storage on backup proxy server). If your local backup jobs report Network as the bottleneck, and you see high load on some backup proxy server NICs when the data was supposed to stay local to the server, your jobs performance is likely to benefit from this behavior modifier. To enable alternative data exchange path, create the DataMoverLocalFastPath (DWORD) registry value under HKLM\SOFTWARE\Veeam\Veeam Backup and Replication, and set it to the following values:
0: Default behavior (no optimizations)
1: Data exchange through TCP socket on the loopback interface (faster)
2: Data exchange through shared memory (fastest)

We will test it in a lab if possible.

Why it is experimental, and what is the roadmap of this enhancement ?

Well, back to the v8 release it was, indeed, an experimental feature. For now the QA team has confirmed it to be valid and reliable, so next major version will have it as a default configuration (at least that’s the plan).
