Test results iozone KByte/s

The test first builds a file 4 GByte big (sequential, initial write) and afterwards there will be read from this file (sequential, read). One step later there will be the same on a random basis to see the influence of the access time (random reads/writes). You can compare 4 KByte block size with a text file with only few letters in it. MP3s and movie files conist of 256 KByte and even bigger blocks. If one for example copies 10'000 text files with a size of 25 MByte it takes much longer than copying a 25 MByte movie file. This is becauseauf of the access time which has a big influence with small files. Big files on the other hand aren't affected by the block size.
