Packages compiled from source are always going to be faster than their binary counterparts. When you compile software from source there are a lot factors that are involved, most importantly the compiler on your machine and your architecture. For example, if you have the latest version on the gcc compiler, your software will perform faster because of optimizations built in to the current version of the compiler that you have. If I'm not mistaken some packages in debian or other distros still use gcc ver 3 because it is much more tested and stable. In quite a few cases, byte code from gcc 4 will be faster than byte code from gcc 3. I hope there was no error in what I was trying to say. -- Amit Uttamchandani <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
