Test case: 4.1.3 much slower than 4.0.20d

Hello,

   on ftp://ftp.mysql.com/pub/mysql/upload/ please find
  file perf_test_case.rar (performance test case).

Within RAR archive there are two files:

  - perf_test_data.sql.gz -- test case's data (~105M of data)
  - perf_test_query.sql   -- test case's query

Test have been done on Windows with 4.0.20d and 4.1.3-beta mysql
version servers.

Query results:

4.0.20d - ~0.14s
4.1.3   - ~10.61s ( ~ 43 times slower ! )

Hope it could be useful if such results is caused by a bug.

Please excuse me, if you already know about that kind of problems.

Regards,
