I just did some 'scientifically' based tests which showed that one must never rely on memory when providing details about what (may have) occurred :-) .
I used a stopwatch to check how long it took to copy a file to (a) a partition formatted in ntfs on an external USB3 HDD and (b) how long to copy to the same HDD but to a partition formatted in ext4.
I copied a 11.437GB file to the ntfs partition using 3 methods and the results were:
1. copy using cp command................. 4 min 59.1 sec 2. copy using mc................................ 6 min 29.3 sec 3. copy using Dolphin......................... 5 min 13 sec
38Mb/sec, 29Mb/sec, 36Mb/sec.
Then I copied the same file to the ext4 formatted partition and the results were:
1. using cp command....................... 2 min 17.3 sec 2. using mc...................................... 2 min 18.1 sec 3. using Dolphin............................... 2 min 18.2 sec
All three about 83Mb/sec. So ext4 is more than twice as fast. I would ignore the differences between cp/mc/dolphin - they're interesting, but not in this context. I would use 'dd' to test IO instead - dd if=infile of=outfile bs=xxxx Try varying the blocksize to see if it makes a difference. You could also try using another filesystems - xfs or jfs instead of ext4. Then redo your test. If they show the same performance as ext4, ntfs is just slow, methinks. -- Per Jessen, Zürich (3.1°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
