I like to know what are the disadvantages/advantages of having ftp server doing the compress during the download and uncompress from the upload.
You know the answer to this is, as always, "it depends." With FTP or any other transmission - you can even extend it to include tape -, it depends on the speeds of the wire and of the CPUs. Assuming a file will compress decently - jpeg, rpms an debs don't - then you will find it quicker to compresss, transfer then decompress, if the link is slow. An extreme example, but one I have to live with, is transferring files through my modem. It doesn't matter how slow the CPU is, compression is worth-while. OTOH when transferring across the LAN, compression's never worth-while, I can transfer faster than I can compress. It might depend on cost too; I can imagine the proud owner of a Zed deciding there are better uses for the CPU than compressing files and instead preferring to plan around the transfer (or deciding to delegate the task to a desktop peecee). -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Please do not reply off-list ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
