Is your feature request related to a problem? Please describe.

I'm always frustrated when I'm looking at the replication worker code. It takes and object from the storage, decompresses it, unmarshals it and then pushes the result to some other node. It allocates for the raw data, it allocates for the decompressed data, it allocates for the object and all of its fields. For big objects this means a heck of a lot of allocations.

Describe the solution you'd like

Have one per-replicator data buffer for raw data, one for decompressed data, one object. Reuse them. Likely this is not supported by our APIs at the moment, but this can probably be changed.
