I currently only have 2GB of RAM so that is not a factor. My whole reason for wanting to switch to a 64-bit kernel was performance. I do a lot of video encoding, which is a CPU intensive application. What you are telling me though is there are no real advantages to a 64-bit kernel other than the memory? -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
