Github user zwoop commented on the pull request: https://github.com/apache/trafficserver/pull/634#issuecomment-219098651 Basically anything that is in trafficserver which would be considered the critical path. The big exception here are plug-ins, because in many cases there is no better option. But we should avoid STL there too when possible. At least until we can prove that STL is not going to impact performance. And it's more than just allocation, it's really easy to write slow STL based code :). Fwiw, your use case is likely fine from performance but sets a bad precedence.
