I'm running a benchmark now, using two 48GB partitions on a 100+GB drive; one LVM+ext3, one straight ext3. Since the machine in question has 10GB of RAM, it will take a while, since bonnie++ defaults to using twice the amount of RAM for the test, to remove the RAM cache from being a factor. Looking at this seeker program, I think comparing the small /boot partition to the larger / partition isn't really valid, since the seeks are going to be over a larger surface on / than on /boot. I'll post when it's done, or tomorrow morning if it's not done tonight. System is running CentOS 5.5 x86_64, but I also have a 32 bit F14 system in the midst of updating that I can try it out on, too. Once the ext3 benchmarks are in, I'm going to migrate to ext4 on both the straight 48GB partition and the 48GB LVM logical volume; I'm going to time the migrations, and rerun bonnie++ on the resulting ext4 filesystems. -- 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
