Hello Matthew, I have no swap defined....and so far have only used ~ 2GB of RAM when I did the latest C++Project for a client.... I am not worried about the size, I am worried about the number of writes. I tend to write my software modularly...so I don;t think this latest project is going to be too heavy on the ram either. I'll add the noatime flag to the tmpfs mounts.....I wasn't aware that you could have additional flags on their mounts..... Thank You very much for the reply...I really appreciate it.
