-----------------------------------------
Hi [~dgvozdenac]. Thanks for taking this up.
It seems like a similar issue happens with compaction metrics.
There was some code changes in these areas in recent versions. I think a good
start would be to inspect the code in {{trunk}} to check where streaming and
compaction size metrics are updated, and if they're being done incrementally or
only at the end of the operation.

> Currently the inbound and outbound streamed bytes metrics are incremented
> after each file is streamed, what doesn't represent the current number of
> bytes streamed since it can take a long time for a large file to be streamed.
> We should update the metric incrementally as data is streamed.
