Thank you for keeping me informed. I appreciate your proactive approach and understand the importance of exploring different angles for optimization. Your patch is indeed fundamental to our ongoing work on the lock-free xlog reservation, and I'm eager to see how it can further enhance our efforts. I will proceed to test the performance impact of your latest patch when combined with the lock-free xlog reservation patch. This will help us determine if there's potential for additional optimization. Concurrently, with your permission, I'll try to refine the hash-table-based implementation for your further review. WDYT? Regards, Zhiguo
