| ### Boost performance during cluster restore and scaling with file copy based initial sync |
There was a problem hiding this comment.
Additionally, as a highlight - I think it'd be good to add a screenshot of performance results (once we have it) and state what's the minimum database size that FCBIS provide benefit (logical sync is actually faster on small databases).

The early test results suggest that there is performance gain only in case of really big instances. For small instances logical sync might be faster because the data is much smaller than wiredtiger's binary logs.

We need to wait for more test from @olexandr-havryliak - we should have it before GA :)

| You can now select how a newly added or a restored replica set member synchronizes the data from other members - via logical or file copy-based initial sync. File copy-based initial sync copies physical files from the source node. This sync method is faster than the logical one and it reduces your maintenance time on scaling your cluster. | ||
