FTP Transfer Speeds on Local Computer

FTP Transfer Speeds on Local Computer

For some testing, I'm running an FTP server on my computer. I then connect to that server with a client running on the same computer. When transferring files, it seems to peg out at 35 MB/s. Is there anyway to speed this up? When I tested it using FileZilla FTP Server, I increased the buffer sizes to as far as they could go and performance wasn't affected. IIS transfers at about the same rate pretty consistently...
