It sounds as if something in the 2.5 kernel has broken evolution. Does this happen every time you reply to a message or just the first time? And if you reply to a message, then quit evolution, then restart evolution then reply to another message, does the same delay happen? The above tests will eliminate the IO system at least. If the delay is still there when all the needed datais in pagecache then please run `vmstat 1' during the operation and send the part of the trace from the period when the delay happens. I'd suggest that you launch evolution from the command line in an xterm so you can watch for any diagnostic messages.
