I have downloaded LR 12.1 evaluation from HP site and tested AJAX Truclient protocol for a web application with 5 users.
Observed high CPU utilization for AJAX Truclient protocol – IE. Each TcWebIELauncher.exe instance is taking 15% on average per instance, for 5 concurrent users CPU utilization is around ~ 75% and test is failed and stoped with error “Error: CPU usage for this load generator has exceeded 80%” after 20 min test execution. Results were also not saved for the test executed. Used different load generator also and observed same. Can you please advice to run the test with out any failure for longer durations.
