While preforming a `pacman -Syu` on my RPi2, I find that the operation pauses after packages start getting unpacked if there is a number of packages to install. It seems as though the SD card I/O has been saturated by the unpacking operation (my hardware is a class 10 card). I haven't experienced this on the B+ model. Do others experience this?
If I'm correct that the cause is saturation of the I/O, it because the processors in the RPi2 is just faster at serving up the data to page out to disk and now, the disk writes are the bottleneck whereas on the B+ model, it was CPU limited? Thanks for your comments and insights.
