I've looked at /usr/share/doc/prelink-0.3.3/prelink.pdf and one of the first thing said is that "it speeds up the launch of Open Office by 5 sec on a p3 650Mhz" ... Of course it doesn't only do that, but I'm not sure I really need it. Are there real advantages of using prelink in Centos for server purpose ? (actually a ssh gateway, but it's the same on a mail server) Thanks. kfx.
