ntfs-fuse performance

[nuclearstrenght]

I'm experiencing very high CPU usage when reading/writing on a fuse (automounted) ntfs partition, it's this normal? it use 100% cpu of 1 of 2 opteron 1.80ghz!!
it's a big partitions on entire disk 300GB being used for p2p temp and data....not a good setup but needed

Will try to help.
Fuse ? sftp ?
Or just a mounted ntfs partition and dumping files there.

Either way reading / writing and using 1 core / 1 cpu of 2 is not normal unless it is doing maintanace on the drive or something but the cpu is much faster than hd so either something else is using it up or something is wrong with ? fuse ? or the ntfs partition writing access.

Only if compiling does your cpu really get used. Is the hd having bad sectors or is it damaged , is fsck doing repairs or is the cable bad connecting the hd ?

Only disk repairs can try to use up cpu cycles or virus scanning slows my windows partition down as I get into windows.

Improving hd performance little bit:
I have read in gentoo forums about in fstab you add a option to the hd commit=60 and for 60 sec's the hd transfers is highest priority and this improves performance etc but will still use max 60% if even close to 60% at all.

p2p and file trasnfers will torture the hd not the cpu and if the p2p software uses up the whole cpu the settings is wrong either in p2p or linux disk management ??

I used it on my swap and root just to test it.

Code: Select all

/dev/sda3               /                       ext3    defaults,user_xattr,commit=60,noatime     1 1
/dev/sda2               /boot                 ext3    defaults,user_xattr                                  1 2
/dev/sda4               swap                 swap    defaults,commit=60,noatime                   0 0
tmpfs                   /dev/shm             tmpfs   defaults                                                 0 0


Hope some of this gets you to the error / fix.

It's a NTFS partition mounted with ntfs-fuse.
high cpu usage came with no maintenance operation on the drive, just normal p2p reading writing to disk, so this is too heavy as cpu usage, somwthing's wrong there

will try your suggestion, dark_mage suggested me on other thread to use ntfs-3g, will also try this to see in performance goes better.

I guess the problem is p2p apps related, bonnie++ showed normal filesystem performcance and cpu usage during testing was normal (around 10%).

let you know outcome

ntfs-3g is much better using it myself.

Best of luck hope you get it fixed.
