> We also have this same issue in our organization. Our application is being quite limited in its concurrency burstability because of the lock contention. Here's a sample mutex blocking profile taken from a real production runtime under high load. > <img alt="Screenshot 2026-04-16 at 3 06 16 PM" width="786" height="1249" src="https://private-user-images.githubusercontent.com/2899204/579524619-23281465-b323-4e25-9df0-d227c78be502.png?jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.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.igqHxDqSb7datH3oWqWr_pMs7vIsvebQXAtf7D82gB4";> I could be misinterpreting the image but it looks like `otelgocql` might be responsible for a significant part of the lock contention in your case no?
