I found this in the wikipedia which does not bode well for the argument of FUSE versus in-kernel thinige:
Performance
Benchmarks show that the driver's performance via FUSE is comparable to that of other filesystems' drivers in-kernel,[6] provided that the CPU is powerful enough. On embedded or old systems, the high processor usage can severely limit performance.[7] Current versions often show 100% CPU utilization on dealing with big files on fragmented NTFS file systems.[8]
It actually agrees with what we said :-)
You do not see speed degradation _if_ the CPU is powerful enough. In other words, you need a powerful CPU to use FUSE fast. And this is specially true with ntfs-3g.
Sorry, but right at this moment my finances do not permit me buying a Cray :-) . Maybe next month, perhaps :-) .
And I think that you not also you not only need a powerful CPU, but also fast memory and buses.
Ummm, an 8-core 3.6GHz cpu with (16GB of) 1866MHz RAM and with a bus which can do 5.2GT/s still too slow, eh? Ah well, next time I'll do all this downwind so that perhaps I'll get some assistance from the wind to speed things up :-) .
This leads to the question whether will all the fiddling about with changing where the USB devices are now mounted (in places other then the normal /media) and other stuffing around with changed paths this has a detrimental effect on the way ntfs-3g is now handled in openSUSE.
No, not at all. That would not have any effect at all. Mounting options, yes.
Another posibility is USB3. I don't know if the design works in hardware or needs lots of CPU assistance. Some of the USB2 designs need more CPU than others. The wikipedia may talk about this.
(BTW,in case someone brings up the issue of the performance being hampered because the ntfs partition(s) have not been defragmented, well before I redid the tests a short time ago I defragmented all ntfs formatted partitions. The results were almost identical to those of yesterday.)
Your partitions were fresh, you said, so that should not be an issue.
But the partitions from which I was copying the files were not and which is why I defragmented them just to see if that made a difference. Leave nothing to chance, I always say :-) .
