Real-time Compression
Need to get more performance on your uploads and downloads? Serv-U supports on-the-fly data compression which can improve the transfer rates on many files by over 50%!
XCRC Support
Nothing's worse than successfully completing the download of a file from a server that doesn't work! It forces you to begin the arduous process of figuring out if the download was corrupted or if the source file has a problem. With XCRC command support, you can quickly verify that the file you downloaded/uploaded is identical to the source file.
