How fast is fscanf?

I had an application where I was reading a 3GB text file into memory, directly from and SSD. Using fscanf the speed would top out at around 100-150MB/s. Only after I've switched to fread the data was actually read at the maximum speed of the drive - over 400MB/s. I guess it's due to parsing fscan is doing.

Hint: It's the way data is read when using fscanf.

Hint++: Parsing is not the bottleneck.
