I am doing a readtable() on a big file. However, I don't see much of a disk activity. The files loads but at a much slower speed that I am expecting. The disk activity shown by windows 10 task manager stays around 1% at a rate of 4.4 MB/s.
Note that this is an SSD drive as the windows task manager says, I am expecting much higher disk activity than this.
It seems like something is limiting MATLAB to read from disk.

With 64GB ram Windows can easily cache a 4GB file. The first time you run the code, or when another program accesses the file may be the only time the disk is read.
