Not at all. Shreddermark has NO problems. Shredder like DIEP just uses your RAM more efficient than Fritz&co, however unlike DIEP, shredder is doing it at a way higher nps than DIEP. That means that the number of random accesses to the RAM is really a lot bigger than it is for Fritz&co. I fully understand this from Shredder and i fear the day already that processors get a lot faster without having a L3 cache of say 64MB :)
