The common wisdom is that EXT2/3 are not affected by fragmentation, but without much real-world proof that this is so. The EXT2/3 filesystem metadata was designed to be not much affected by fragmentation, but that says little about the file data. I read an article / webpage (that I can't find right now) by someone who decided to experiment with new and used EXT2 filesystems, and found a substatial slowdown. He was inspired to try this because he noticed that his computer sped up when given a fresh filesystem. You could try backing up and restoring to a fresh filesystem. If you spring for a new computer you'll back up and restore to the new computer. Either way you'll get a fresh new filesystem. -- ____________________________________________________________________ TonyN.:' The Great Writ <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' is no more. <http://www.georgeanelson.com/> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
