What are you doing to these files? are you just looking at file names? are you stating multiple times for size mod date etc? are you slurping the data? Show us some code. Off the top of my head, I can think of a few things that can go wrong here, for instance grabbing multiple items such as mod time size etc can make multiple requests over the network for each file unless you do it correctly If you are slurping files to do proccessing of them *welp* the network is going to be way slower than a local hard disk. Give me more info on what you are doing and I can give you some pointers.
