Description

On my private instance and tech-preview, I get:

On my private one I am already using:
tmp_table_size = 128M
max_heap_table_size = 128M

On TP:
tmp_table_size = 64M
max_heap_table_size = 64M

So 64MB seems to be a hardcoded(?) value, but should probably be more?

Research direction

Start by tracing where the server info dashboard reads and presents tmp_table_size and max_heap_table_size, then search the repository for the 64M value or related temp-table guidance. Compare the displayed suggestion with the configured values in the report. Done means the source of the 64 MB value is understood and the issue has a verified expected behavior.
