is it safe to increase the maximum number of simultaneous connection in web browsers?

by tweaking the windows registry settings, changing the default value, which is "2", to "10"? which practice do you think is better for internet surfing performance?

 

You may get a performance boost in the sense of faster loading webpages, but some webmasters don't like this tweak because it can also put a heavy load on a webpage when many people use these sorts of tweaks. In extreme cases webmasters may also block you from future visits.

 

It is safe. See if increasing to 10 makes a difference.
