Still true today. Copying about 180 MB of smaller files (pictures) to a NTFS partition (filesystem) inside TrueCrypt. It took 20 minutes. I partition the same mapped device -- format it -- to exFAT, and it takes 26 seconds. So it took 26 seconds to write that same data at 7.2 MB/s and it took 20 minutes to write the same data at 160 kB/s. Just incredible. Just incredible for something that has been around for so long.

This is one of those issues where I can idly conclude that either the developers don't eat their own dog food (use their own product), the issue is a legal or social problem, or intentional. I don't think my use case is particularly strange, and this problem is a show-stopper.

[Bug 392204] Re: Huge CPU usage by mount.ntfs process
I was almost constantly getting ~95% CPU spikes from the mount.ntfs process, according to 'top'. Disk fragmentation or big files (some files as large as 16GB) were not causing the issue. Defragmentation of the disk, using a Windows workstation, didn't change anything performance wise whatsoever. What fixed it for me was physically mounting the hard drive to a Windows workstation and using CHKDSK. The disk wasn't damaged or anything but apparently ntfs-3g causes 'free space marked as allocated' in both the Master File Table (MFT) and volume bitmap. Once this is fixed the huge spikes are gone. At least for me.

Well, sure.

Is it Wubi that's causing the problem (which didn't exist in my previous 11.04 install). Is it a new version of ntfs-3g that caused this bug to occur sometimes? Is it a symptom of multiple causes across Ubuntu, or is it a single problem that people have no interest in fixing?

Wrong, Sam. If you were to create a new "really big" partition for use on a mobile rack or an USB-disk for data exchange with the "outer world", what would be your choice?

I have the same problem (running Wubi with Ubuntu 12.04) and it's rendering my computer virtually unusable. I have also had this problem on a different computer running Wubi with Ubuntu 11.10. I have been using Wubi with Ubuntu 11.04 on the same machine with no problems in the past. All have been clean installs (i.e. not upgraded from previous versions). My version of ntfs-3g is "ntfs-3g 2012.1.15AR.5 integrated FUSE 27" (though the problem has existed for other versions after Ubuntu 11.04). mount.ntfs appears to run whenever write-to-hard-drive is occurring. Additionally, it blocks most applications from running (presumably as they all eventually need to read/write to HDD), resulting in greying out of the application window for a few minutes. It's especially problematic when doing >1MB file operations (e.g. installing packages with apt-get). The Windows install is barely used, so it's unlikely to be highly fragmented. I have tried various things mentioned in this thread to no effect (I came unstuck with the suggestion to backport ntfs-3g as Ubuntu refused to backport fuse/fuse-utils for some reason). I agree that it's bizarre that this bug has persisted for so long without a fix, especially since (in my experience) it make Wubi unuseable. I suspect that my solution will eventually be to give up on Wubi and create a new partition for Ubuntu, but it's frustrating that I'd have to do this when previous versions have worked fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/392204 Title: Huge CPU usage by mount.ntfs process To manage notifications about this bug go to: https://bugs.launchpad.net/ntfs-3g/+bug/392204/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've recently switched over from Windows to Ubuntu (11.10) and was pulling my hair out trying to figure out why two programs we're hanging and being very unresponsive (Filezilla and VirtualBox). Turns out that it was that I was running them off a NTFS partition (and therefore having ntfs-3g taking 70-100+% of CPU as others have said).

I have the same problem on K/Ubuntu 10.04 (2GB Ram, E6750, ASUS P5B Deluxe). I have 4 SATA hard drives, with system on the first one (ext4) and various data on three others (ntfs). Copying 200GB of files from ie. second to third drive makes system nearly unusable. I tried the 2010.8.8 version of ntfs-3g, I got slightly better performance, but still very high: around 50-60% of CPU usage by monut.ntfs and about 20% by mc during file copying from one drive to another. -- Huge CPU usage by mount.ntfs process https://bugs.launchpad.net/bugs/392204 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I went to http://www.tuxera.com/community/ntfs-3g-download/ and grabbed the rc.tgz I made a debian package with the result, modified the version so that it would not be "upgraded" and installed it. mount.ntfs barely makes a blip in System Monitor (ksysguard) on KDE. One could do a ./configure make sudo make install with the extracted tarball, but I like the packaging of a deb so it can be easily removed. I did have to remove the associated "lib" file that accompanies ntfs-3g on ubuntu.

[Bug 392204] Re: Huge CPU usage by mount.ntfs process
Additional testing reveals that writing really large files must simply be more likely to reproduce the problem, but in fact is not a requirement. With a NTFS partition near capacity (around 4 GB remaining), I was able to reproduce the problem by writing a file that is just under a GB to it. When I noticed that it slowed way down several seconds into writing the file, I aborted and freed an additional half a GB more (giving a total of ~4.5 GB free). I was then able to write my file not-so-large file at normal speeds. So it seems this may be due to some odd fragmentation corner case. -- Huge CPU usage by mount.ntfs process https://bugs.launchpad.net/bugs/392204 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here is another scenario which ends up with the same problem. Downloading using Transmission a DVD ISO of CentOS and storing the downloaded file to an NTFS drive (either internal or via USB). After a while, the CPU load is so high that Transmission does not download any more, it just waits (freeze mode-like) for the ntfs-3g to do something (high CPU load) and thus the download is kind of stalled... So, as of now, I have downloaded about half (1.7GB) of the DVD ISO, and when I launch Transmission it is just consuming CPU power (and electricity power) for basically nothing significant. This is a bit frustrating as I do not have the required space on my Linux partition to be able to download the DVD ISO...
