V1.0 (capps): Capps: Beginning of the code base. Isom: Added reread Added rewrite Added read backwards Added lseek+read Added lseek+reread Capps: Added more accurate time collection method. Added alignment in the on chip Cache code. Added change step when passing 16 Meg size file. Capps: Added auto+ to purge on chip cache. kcollins: replaced the lseek+read &reread test with random re more»
