Hi
I intend to use openSUSE for a real time application which requires to write from memory to hard disk 330 MB of data continuously in about 2.56 s. When I write only 330 MB, the write time using Round Robin real-time scheduler is about 1.5 s, almost two times better than using the default scheduler. If I use 10 times 330 MB data and then I average the write time I get about 7 s regardless of the scheduling policy. My first thought is that the disk defragmentation should be held responsible for such performance penalty. Is this the right explanation ? Are there ways to improve the write time when dealing with large amounts of data ?
