It would be interesting to see what happens with a different filesystem, e.g. ext3 or ext4, that doesn't use fuse. If that's not practical because the disk contains real data, perhaps you could create a small partition with one of the kernel-supported filesystems and measure that. If that shows a big difference, check if fuse has enough working memory, or if there's any way to instrument it (I know very little about fuse so I can't help there). Or even try it with a vm-based Windows installation (I know it sounds wierd, but it could be interesting to try). poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
