Loadrunner 12.53 issue with Firefox and chrome while running tests, TruClient for Web prtocol

[Manoj Pathak]

Hi,

I have started using LoadRunner 12.53 locally and am not able to run tests due to below issues:

1. With Firefox: I am able to record, customize and run the script in VUGen 12.53 using protocol TruClient for web but when I run the same script for multiple users in controller I cannot run. The reason is  when all users are launched ( 30 users in my case, ramp-up - 1 user every 5 seconds), the hits/second, throughput, response time graphs do not show anything. But when users are being ramped up the graphs show proper data. The issue appears only whe all the users are ramped up and the test is in steady state. This problem does not appear when I run the same test by changing browser to Chrome. 

I wait for controller to respond and after few minutes I get lots of errors related to connection between controller and load generator ( I am using localhost as load generator)

One more observation, when I restart my machine even Firefox works well for 1st time but when I run the same test again it stops responding once all users are launched.

2. With Chrome: When I run test even for 20 users locally, CPU utilization reaches 100% and does not come down. I tried 5 users as well and it still reaches 100% though it comes down sometimes.

 The application users around 200 Megabytes per user but Physical memory is not a problem because it was never used more than 50% but CPU is creating issue even though I have i5 quadcore processor.

I am using Windows 7 64 bit, I used Windows 2003, 2008 as well but none of the above issues seem to be resolved. 

Please help me to solve the issue.

Regards,
