I have yesterday (20200106) registered and bought current version (14.24) of GSA SER. Because I yet need to more details for the Project, I just started with adding and testing proxies. No matter what was the threads value set to, it was still freezing. During the time of proxies scrapping and testing was not running any other application. In the Task Manager was shown, that the impact on the system is "Very High". The Configuration of my system is as follows: Windows 10 PRO 1909 64-bit, AMD 3,9GHZ, 8GB DDR4, 2TB SSD, 500Mbps).
note: this was experienced even in older versions during summer (not sure what exactly was the version though).
Do you have any hint, how to prevent this? Thanks for your answers
