Thanks IDM super users and developers.I suggest that you don't change it to no more than 8 threads. Because some servers might find more threads other than 8 will be offensive and they might reject server requests. Whereas the IDM team suggests that users should not change the thread count. Or if you still wish to change go to http://www.internetdownloadmanager.com/register/new_faq/functions8.html page.Every time my IDM (internet download manager) starts, I see only 8 threads running. How can I run 32 threads at the same time ?
