      7% regression in OperationThroughput in linkbench/ LOAD_PHASE_THROUGHPUT_OVERALL test is observed after WT-11398 changes. The changes in WT-11398 are actually implemented to improve the eviction performance. This ticket is to investigate the root cause of the regression.

      This is a follow-up ticket from BF-30668.

      Here is the system performance patch build link after WT-11398 revert from the mongo master.
