c-taylor opened a new issue, #8781:
URL: https://github.com/apache/trafficserver/issues/8781
Under load you can see the pthread calls in the functions:
`ink_thread_(key_create|setspecific|getspecific|key_delete)`
Start to feature in perf traces.
Please review and consider migrating native C11 `thread_local` which should
be faster, and _may_ also be copy free.
A good example of where this is currently observed is in `TSHttpTxnReenable`.
```
92.40 │ mov Thread::thread_data_key@@Base,%edi
1.59 │ callq pthread_getspecific@plt
```
