Thank you for replying.
In LoadUI, I am sending 9 different web service requests using 8 SoapUI projects at about 2-3 requests per second.
I cannot send you the soapUI project files (there are 8 of them) since they have passwords, but i am sending you the LoadUI file. Would the WSDL files work?
It's not so bad if I remember to restart LoadUI before running each test and occationally reboot my PC.
Overall, I'm very happy with both LoadUI and SoapUI. I'm attempting to get my company to buy the pro version of LoadUI. I have already purchased the pro version of SoapUI.
