In recent GIDS presentation, I was asked can I name potential bottlenecks for performance. I was taken back to my collage life with this question. I remember that I have memorized following names as potential bottlenecks.
Today when I look back at this, I still think the same reference is correct. It seems very interesting that technology has really moved ahead but the essence and basics of any subject are still same.
Can you think of any other kind of bottleneck, which is not subset of above five topics which I have mentioned.
