Today, we experienced slowdowns in a production environment in the processes running there. We investigated the reason for this loss of performance and found that during the execution of one of the components, an excessive call was made to the thread_stmystate_fast function. Memory addresses were assigned more times than the process requires. This application was running on an earlier OS version, and there, the calls to this function were much lower, which did not cause any slowdowns in the process.

I appreciate any guidance you can provide to resolve this error.

Sincerely,

Alejandro Rodriguez Mancera

Good morning:

I'm reviewing the compiler being used on the AIX 7.3 server where the component experiencing the error is running. The question is, can we identify the library or parameter that calls the thread_stmystate_fast function, or is it called by the runtime?

We're focusing on identifying why this function is called so many times in this environment. In AIX 7.1, it's called, but not as often as in 7.3; the ratio is 1 to 20.

Thank you very much for your support.
