Performance issue in expect library on AIX 5.3
Hi All,

I am getting a performance issue in expect5.43.0 library on IBM AIX 5.3. When I have used exp_fexpectv call for pattern matching with the expect string, the execution latency of the call is approximately 200 ms. In that way, I am able to complete only 4 or 5 transactions per second using the expect library. Even when I bypassed this call and used a separate code to read the file pointer opened by exp_popen, the latency is not reduced.

When I am using expect 5.40.0 expect library on solaris 8, I am not facing this problem.

Do I have to use expect 5.40.0 library on AIX to resolve problem? Or Could this be because of any issue with the AIX 5.3 installation? Please suggest.
