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? Probably. Never mind your eight cores, it's only one that matters when the workload is single-threaded.
Well, as I mentioned 5 or 6 cores were involved and not just one single one. I haven' seen anything to convince me that only 1 single core was involved or should only be involved.
Basil, it's a pretty longwinded thread by now, I am having trouble working out the current status.
The thread has taken on a life of its own. Or as they say on YouTube, the thread has gone "viral".
Am I right in thinking this is still about explaining why you get different IO-rates on two different filesystems (ext4 and ntfs)?
Yes, from my point of view the question still remains as to why there is such a difference between transfer rates. The entry in the wikipedia is indicating that such a large difference should not exist. I am not a technician, but to me to read a byte of data and then write it to another device and then to verify that what was written to the destination is the same as the original doesn't require a ming-boggling process of what some people are indicating happens with FUSE vs the kernel-thing.
