Package reload timing and "processing unchanged namespaces"

[cci.mimorgan]

My NSO 6.1.2.1 instances with an 8GB CDB (ram size) currently take over 90 minutes to reload packages with even the most minor change. The devel log will sit at a "processing unchanged namespaces" message for over an hour with no other output in any logs:

<INFO> 4-Jul-2024::22:40:53.186 nso ncs[120229][<0.1617.0>]: devel-cdb upgrade: processing unchanged namespaces
<INFO> 4-Jul-2024::23:47:10.173 nso ncs[120229][<0.1617.0>]: devel-cdb upgrade: completed unchanged namespaces

 Is this expected behavior? If not, how do I see what's going on here to diagnose the issue?

though the schema has not changed, but there could be nodes that are affected by schema change in other namespaces, e.g. an instance-identifier, so NSO needs to check corner cases like this.

if you want more logging to show progress(or just to show the upgrade is not stuck), please create an enhancement request via aha.
