I installed a D-link DNS-323 NAS device on a small P2P network and mapped 3 Windows XP computers to the shared folder. It is so slow to do everything. It takes about 30 seconds to even open a directory to view files and 30 to 60 seconds to open or save a 4MB Excel file. I know these Low end NAS devices are not the fastest but this seems completely out of line. Any suggestions? I updated the firmware with no change.
