Xfce 4.12
I am trying to copy he new Xfce Live ISO (1.4 GB) over
to a Samsung usb 3.1 stick. It is taking FOREVER. And
this is typical.
Is your usb also slow by any chance?
My kernel is 4.18.16-200.fc28.x86_64
I just copied a 3GB iso to a FAT32 partition:
real 2m6.738s
Copying to EXT4 and syncing took almost 3 mins.
So I don't see this problem with my laptop.
Check the mount options, maybe there is something like sync set,
although it still shouldn't take that long.
Try running "iostat 5" while it's copying to see how much I/O is happening.
Hi Sam,
Wow! You sure called that one! Thank you!
I ran to an fat32 and got:
# time cp Fedora-Xfce-Live-x86_64-29-20181029.1.iso
/run/media/tony/FAT32TEST/.
real 2m0.151s
user 0m0.005s
sys 0m1.483s
This is the ntfs stick mounted from the desktop:
/dev/sdc1 /run/media/todd/xxxx fuseblk
rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096
0 0
It was fast.
This is the way I originally mounted it:
/dev/sdc1 /mnt/xxxxx fuseblk
rw,sync,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096
0 0
And I do see the "sync".
This is the code where I mounted it:
mount -o users,exec,sync $Device $Target > /dev/nul 2>&1;
With "sync" removed, this to a 3.1 port to the Samsung in question:
# time cp Fedora-Xfce-Live-x86_64-29-20181029.1.iso /mnt/Rent-A-Nerd/.
cp: overwrite
'/mnt/Rent-A-Nerd/./Fedora-Xfce-Live-x86_64-29-20181029.1.iso'? y
real 0m8.254s
user 0m0.014s
sys 0m1.318s
And to double check, unmounted and mounted it somewhere else:
# sha256sum Fedora-Xfce-Live-x86_64-29-20181029.1.iso
/run/media/todd/RENT-A-NERD/Fedora-Xfce-Live-x86_64-29-20181029.1.iso
