5% performance regression in retryable writes workloads with 8 threads on linux-1-node-replSet

This is a break-off ticket from BF-10453. We have noticed a 5% regression in MongoDB branch compared to v4.4 branch for retryable_writes_workloads benchmarks. The aim of this ticket is to:

• Verify the regression still exists
• Next step would be to analyze the t2 data between v4.4 and master branches and confirm if the regression is related to WiredTiger.
• Create a WT ticket for possible improvement.
