having to open each table.frm (and in which my test runs, I have purposely read a very high number of tables compared to “Table-open-cache” variable). When running only sysbench, there is a high number of cache hits (~99.98%) and a low number of “misses,” which means the table_cache is big enough for the workload.

As noted configuring more should not have a major impact on results as depending on the number of virtual users used in the test most the warehouses will be idle (and ideally most of the warehouses you are using will be cached in memory in your buffer cache so the I/O to the data area is minimal). . .
