AFAIK, fragmentation only happens in Linux when your hard drive is quite full. It's normal, since with little space free and randomly spread across the HD, you can just fragment big files to write them. And sure, fragmentation degrades performance (if anyone has a small partition available, a simple test like formatting the partition, copying enough files to fill it up - e.g, your music collection- then delete some files to leave about 10% free space. Now copy a tarball and time how much it takes to untar. Then format the partition again and try extracting that same tarball again with the partition clean. The difference is in the range of 40s vs. 8s).
So to keep the system fast (not only regarding boot time) it's always good to keep your HD clean and as empty as possible. It makes a big difference (though convenience vs. performance must be taken into account too, of course).
