Your solution is producing performance bugs in production that you did not see in staging and test environments. You want to adjust your test and deployment procedures to avoid this problem in the future. What should you do?

Performance bugs appearing only in production, but not in staging or test environments, strongly suggest that the staging and test environments are not accurately simulating production load. Increasing the load on these environments will help uncover performance bottlenecks and issues before they reach production. Deploying fewer changes or smaller changes might reduce the frequency of new bugs, but it doesn't address the root cause of why performance bugs are missed in testing. Deploying changes to a small subset of users (canary deployments) is a good strategy for mitigating the impact of bugs, but it's a production-side mitigation, not a pre-production testing solution for uncovering performance issues under load.
