Loadrunner 12.01 and Truclient Ajax - High CPU

Hi,

I ran a 4 VU test (to verify script) using the Truclient Ajax for Firefox protocol. I noticed errors relating to High CPU (> 80%) usage on the controller/injector (all in one). 

My machine I am using is a VDI - Win 7, 4 GB Memory, CPU 2.2 GHz. 

Is the recommend option to use the new "Convert" function that comes with LR 12.01 to get more users on? I tried the convert function and it does generate a HTTP script for me but found some bits missing in generated code (i.e. the whole logout bit was missing). 

Any advice?

Regards,
