The reduction in speed with later Tk versions does not seem to occur on Linux. See the below table (times are microseconds per iteration - tested using wish):

+------------+----------+--------------+
| Tk Version | clearing | not clearing |
+============+==========+==============+
| 8.6.8      | 197.7    | 183.46       |
+------------+----------+--------------+
| 8.6.11     | 170.3    | 201.6        |
+------------+----------+--------------+

I have not tested on Windows but I don't think it's unreasonable to conclude the performance issue is limited to MacOS.
