[GitHub] [trafficserver] c-taylor opened a new issue, #8781: Replace pthread_* calls with C11 thread_local

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
   ```
