I have filesystems here of simlar sisze with wildly varying file sizes. The 1Tb partition (80% full) with 8000 files in it backs up quickly The 1Tb partition (50% full) with 7 million files in it takes 5 times longer. There is a fixed filesystem time cost of opening each file and therefore the smaller the file the lower the average throughput - having said that most filesystems get SLOW when there are thousands of files in one directory.
