The purpose of the test was to ensure that the SX (update) mode of index tree and buffer page latches are being used. The test has become unstable, possibly due to changes related to buf_pool.mutex and buf_pool.page_hash, or to the use of MDL in the purge of transaction history. In 10.6, the test depends on instrumentation that was refactored or removed in MDEV-24142. The use of different latching modes can better be indirectly observed through high-concurrency benchmarks. For MDEV-14637, a performance test was conducted where the finer-grained latching and BTR_CUR_FINE_HISTORY_LENGTH were removed. It caused a 20% performance regression for UPDATE and somewhat smaller for INSERT. Any new problem with latching granularity should be easily caught by performance testing, or by stress tests with Random Query Generator.
