Testing filesystem performance read/write numbers of files into overloaded directory with up to 7 million files.
/dev/shm/ tmpfs in memory filesystem
The null model test. This is the RAM memory filesystem '/dev/shm/'. Performance remains constant despite numbers of files in the directory.
xfs filesystem
Writing performance declines rapidly, reading performance remains constant.
ext4 filesystem
Both read and write performance drop off between one and two million files in the directory.
