Highly experimental patch
Using Connection: Keep-Alive did not have any significant performance improvements, I'm closing the bug for now. |
Description of problem: Each request inside WBEMConnection opens new TCP connection to CIMOM, which includes TLS handshake (if enabled). This slows down whole communication a lot. Version-Release number of selected component (if applicable): pywbem-0.7.0-16.20130827svn625.el7.noarch How reproducible: always Steps to Reproduce: import pywbem c = pywbem.WBEMConnection("https://localhost", ("root", "opensesame")) while True: c.EnumerateInstanceNames('LMI_Identity') Actual results: in wireshark, I see lot of separate TCP connections Expected results: One TCP connection with HTTP keep-alive enabled.
