It's rather annoying you can do nothing during extraction and checksum checking stages of a port build. The bigger downloaded file, the longer it takes (and it's done in a single CPU thread, so it can be long). For example, huge www/chromium take several minutes on these stages on my system. System freezes and for some seconds even mouse pointer is not reacting, windows switching in GNOME/ MATE is almost unresponsive, not to say about other activities.
May be some system options? Or is it a known problem?
