> I have a problem  related to the speed of copying files in C++ on linux.  I need to automate a process to copy files from one directory to another for media management.  Anyway, the following code is what I have been using and it is not nearly fast enough.  The entire focus of this application is speed.  In fact in Windows, I am getting at least 5 times the speed from a VB app that I am using.  I know I must be doing something wrong.  I am compiling on a one processor machine and moving it to the test equipment which has four processors and 4 gigs or RAM.  I wonder should I compile it there to see if it runs better or is there a better method for copying files from one directory to another.  The file system is Reiserfs on a gentoo installation.  The machine that I am compiling on is ext3 on Redhat.
