Hello everyone, thank you for the replies.
Sebastian, the chunk size is roughly 4*10^6 samples, with two byte per sample, this is about 8MB. I can vary this size, but increasing it only helps for much smaller values. For example, when I use a size of 100 Samples, I am much too slow. It gets better for 1000 Samples, 10000 Samples and so on. But since I already reached a chunksize in the region of megabytes, I have difficulties to increase my buffer size further. I also have the feeling that increasing does not help in this size region. (correct me if I am wrong...) Chuck, I am using a Windows XP system with a new (few months old) Maxtor SATA-drive.
