I recommend GrandPerspective, it seems to make the same (with more alternatives which you anyhow don't seem to need), but is fresher. I am using it for ages now, there was a time in Mavericks it didn't work, now it goes well. I guess what takes time is the reading of the disc, an app without the details of kind of info won't, as far as I think, really take much less. It gives more info than you need, but you can ignore that, as long as you find what you need. Although it is from 2006, I think it isn't bad coded, and it still works on my 10.9.

If the disk is big, it's slower than on a little one, and of course, on an SSD it is really fast. The top alternative according to alternativeTo (as well as my own sample usage) is JDiskReport. I think Disk Inventory is as fast or slow as any of the others.

Starting with macOS Sierra, macOS comes with an built in app from Apple called Storage Management, which is a part of the System Information app. It's a fast, easy way to find those large files cluttering up your drive and clearing them out for new, better things. OmniDiskSweeper is really great at what it does: showing you the files on your drive, in descending order by size, and letting you delete them easily! It scans your disks as quickly as possible and shows you the facts - if a file doesn't make the cut to stay, just click the big Delete button and be done with it.

OmniGroup offers a free utility called OmniDisksweeper which lists files/folders sorted by size.
