Description
I'm opening this ticket following on from MB-50615 in which we see a significant performance decrease in cbbackupmgr restore when TLS is enabled.
When we look at the cbbackupmgr logs we see that the KV Data Transfer phase (which AFAIK is a lot of SetWithMeta calls performed using gocbcore) takes ~2.4x longer when TLS is enabled:

We do of course expect some overhead for enabling TLS, the question is whether this much of a slowdown is reasonable.
