[SOLVED] low speed & high CPU usage copying files between two HDD

Both HDD are connected by SATA to the MB. One is in NTFS format (shared with windows 7) and the other one has different partitions.
I'm trying to copy one file (230 MB) from an ext4 partition to the NTFS HDD. The speed is about 40 kB/s and on the system monitor, I can see how one of the cores is about 100 % of usage!
I have done these operations lot of times and never happened something like that.
What should I have to look?

Why are you mounting a flash drive on your fstab? (unless its always in your PC when you boot....or you never want to remove it?)
unmount the usb (/dev/sdb1)
Then I think try hash out that line for the usb (/dev/sdb1) and install ntfs-3g and mount with
mount.ntfs-3g /dev/sdb1 /mnt

Permissions problem copying files between two Macs

I've run into a strange problem when trying to copy files between two networked Macs. Some background facts: We have two Macs at home each with three accounts. Two of the accounts are regular user accounts (my wife's and mine, call them "K" and "B" for short) and the third is an administrator account (we'll call it "A"). I have a .Mac account, which I use to sync between the two Macs. The other accounts do not. The user accounts B & K were initially set up on the second Mac via the Migration Assistant, copying over files and settings. The administrator account was not.
The problem I've run into is that if I am logged in as either user B or K on the local Mac, connect to the remote Mac as the corresponding user, and try to copy files into a folder owned by that same user on the remote Mac, I get a series of three dialog boxes with error messages:
1) "You may need to enter the name and password for an administrator on this computer to change the item named ..." (stop/continue)
2) "The item ... contains one or more items you do not have permission to read. Do you want to copy the items you are allowed to read?" (stop/continue)
3) "The operation cannot be completed because you do not have sufficient privileges for some of the items."
If I go all the way through this hitting continue / OK on each, what shows up on the remote computer at the end is an empty file with the name and filetype of the local file that I was trying to copy, but of zero length.
This only happens when I'm copying from (local.B -> remote.B) or (local.K -> remote.K). It does not happen if I try any of the other pairwise combinations (assuming that I've authenticated properly): (local.B -> remote.K or remote.A), (local.K -> remote.B or remote.A), (local.A -> remote.B, remote.K or remote.A). It happens regardless of which Mac is local and which is remote.
I'm a little baffled. I've tried to search for this on Apple Discussions and other forums, but either haven't been using the right keywords or am coming up blank.
Anyone have any suggestions?
Thanks,
Bob

borbye is correct that this will remedy the problem but there is a way to do it and have your account work. after changing the user UID and group UID to 501 you will have to restart. then when you log on your home folder will still be your default but you will not have any access. Since you are still an admin you can change that. right click on the home folder and select get info click arrow for sharing and permissions. Your old UID account will show up as _unknown delete this user and add your user to it giving yourself read and write privilege. click on the cog on the bottom and select apply to enclosed items. A warning box will appear stating that this process cannot be undone do you wish to proceed? click yes and a status bar will come up. once the bar is gone the process is complete. since you didn't have access to your home folder you cannot save your settings, this is a good thing since your account will not look remotely the same as yours most likely. all you have to do now is logout and then back in. Your account will look as it did before the change with all the access settings and so forth as before the change... minus some permissions due to the overwrite. It's a minor repair to the permissions to some shares considering you will be able to now move files to and these shares without the permissions alert that only creates a 4kb file instead of the real thing. Takes 5 minutes at most. Have fun.

[SOLVED] qemu-kvm high cpu usage when using pulseaudio alsa-plugin

My Arch system is configured to use pulseaudio. When an application connects to the sound server it will use either a native pulseaudio driver, or the pulseaudio alsa-plugin if it using a alsa driver.
qemu-kvm in 'extra' is not compiled with native pulseaudio support. When running guests with sound hardware support, qemu-kvm connects to the sound server using the pulseaudio alsa-plugin.
The problem I'm seeing is high cpu usage on the Arch host even though cpu usage on the guest is low. Also, the guest is often unresponsive for a period of time when opening sound applications like the mixer or playing audio.
My solution is to recompile qemu-kvm with native pulseaudio support. This eliminates the use of the pulseaudio alsa-plugin on the Arch host and fixes the above problems.
An easy was to do this is run:
yaourt -S qemu-kvm --build
And edit the PKGBUILD changing the line:
--audio-drv-list=alsa,sdl,oss,esd \
To:
--audio-drv-list=pa,alsa,sdl,oss,esd \
Finish building and install. Don't forget to add yourself to the kvm group.

Copy Files Between Two Unix Computers

Hi,
I am trying to write a piece of code that will copy bunch of files from one Unix computer on to another Unix computer. On windows it seems to be pretty straight but on Unix I am trying to understand best way of copying the files. I don't have much expertise in Unix.
Is using FTP the only option for Unix?
I am not able to create a FILE object by referring to a file on some other Unix box? I tried new File("//unixbox2/temp/123.txt");
Please let me know the different ways to copy files between Unix computers.
Thanks

IPhoto 9.4.3 high fan speeds/ high cpu usage.

For about a month now, my iPhoto has been acting up. My iPhoto CPU usage idles at about 30% and as soon as I start using iPhoto, the CPU usage can go as high as 430%.. This causes the fans to spin at 6000RPM and eventually iPhoto will slow down and I'll have to force quit.
I have tried:
- repairing the iPhoto library
- creating a new library
- re-installing OSX Mountain Lion
- re-installing OSX Mountain Lion and then installing a fresh copy of iPhoto
- rebuilding the iPhoto library with iPhoto Library Manager
Nothing has fixed this issue. I have exhausted all of my options and I would greatly appreciate any help.
Cheers,
Joey

Did you remember to quit iPhoto before deleting the caches and to log off and on again? WIthout logoff or reboot cleaning the caches may have no effect.
iPhoto is keeping second, hidden cache in $TMPDIR. Try to clear that as well.
You can only open that cache from the Terminal.
Quit iPhoto.
Open a Terminal window and enter
open $TMPDIR
and hit "return".
In the window that opens remove the folder com.apple.iPhoto.
log off and on again, and retry.
Im thinking that this is a software bug.. but I just cant figure out why its happening on a fresh install of OSX / iPhoto. Seems bizzare.
I am using the same iPhoto version on a similar early 2011 MBP Mac without problems. Maybe the file type of your photos and/or videos makes a difference. What media kind are in your iPhoto/Aperture library? Videos? Raw? Jpeg?

High Cpu Usage when file open in Illustrator 9

Hey guys, have had a few problems lately when an EPS or AI file is open in Illustrator 9.0 cpu usage sits between 50 - 100% and clicking around the program is in general very sluggish. All boxes with problems run Windows 2000 SP4. These arn't slow machines either, about 3GHZ dual core, 1GB ram. I know Illustrator 9 is old but it's being used in a business environment so upgrading is not really an option. Thanks in advance for any help.

By "lately" do you mean this is something that started happening recently?
If so, can you remember any changes (updates, service packs, other software, etc.) you might have made to your boxes recently?
Are you updated to 9.0.2?
If not, it's worth doing, and here are the pertinent links:

'Finder wants to make changes' when copying files between two Macs

Hey all,
I've read a few versions of this problem on the forums here but haven't tracked down a solution.
I have two Macs on the same network – I recently got a second-hand Mac Pro, and my Macbook Air. The computers are both on the network and can browse their respective folders and the like, but when I go to copy or sync files between the computers, I get a file permission issue.
Finder on either computer prompts: 'Finder wants to make changes. Enter your password'. At the same time a corrupted version of the file copies to the other computer but with 0 bytes that doesn't open...
Has anyone solved this issue before – it'd be greatly appreciated to hear any approaches!

On the laptop I got 513
Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Problem copying files between two external drives...

Hello, and thanks for any ideas on this one.
I have a punch of .m4v video files on a 1TB Lacie external drive, but re cently bought two 3TB Seagate drives and wanted to move all these media files over to one of the new drives. Most of the .m4v files moved just fine, but I encountered two different issues in the process that I can't resolve.
I'm on an Intel-based iMac (Core 2 Duo), running OSX 10.5.8.
1. Most pressing problem:
One of the video files, when I try to copy, causes the finder windows to completely freeze requiring a hard reboot of the machine to fix. I can get infomation on the file OK, and can play it off the original drive just fine, but try and copy it and all manners of computer death take place. There does not seem to be a permissions issue, and the file isn't flagged as locked.
This command produces no fruit either: $ lsof | grep videofile.m4v
2. Second issue:
This one affects two other files. When trying to move them over, they get approx half way there and then I get a notice that the operation cannot be completed because the files are supposedly in use.
All the googling I can do on that error seems to bring up cases where files can't even start to be moved... but in these two files, they get half there. Or maybe they're read OK but then can't write? Either way the status bars show about 1 GIG or 1.7 copied. I don't know.
I also checked the permissions, the locked setting, used the lsof command, etc... no luck.
About 100 other videos copied over just fine.
Any ideas are greatly appreciated.

Thanks for the response... I tried just now, no luck.
I did at least get an error this time for problem one above before the lock up... lol... error code 36. So far searching for that isn't coming up with any solutions either.

Insufficient Privilege to copy files between two Macs as Admin

File Sharing in Leopard is worthless... it reminds me of how much fun it is to get file sharing to work on Windows.
I have two Macbooks... I'm administrator of BOTH. I set up the userids. I set up the passwords.
When I TRY to link to the shared disk on the other computer, it automatically links without giving me a chance to type my administrator userid/pw. (Although it links as the owner with the correct pw... and even as the owner I can't copy a file from my laptop to the desktop of the other one!)
If I click the "disconnect" button multiple times, sometimes it will present a CONNECT AS... dialog and i can enter my userid/pw (I'm designated as Administrator on both laptops). Sometimes the Finder crashes (netauthagent or something)... I have to force restart the Finder.
If it doesn't crash, I still do NOT have authority to actually copy a file.
I've tried both as AFP and SMB...
What is going on with networking? was this ever tested before it was released.
Things like this (not to mention HELP windows that obscure the screen and can't be hidden and 100s of other equally annoying things) is a bad joke and more annoying than it should EVER be!

Kswapd0 almost constant high CPU usage

Hello,
On my Eagle M2, I see kswapd0 using almost constant 50% CPU usage with the latest AOSP.
Can this be related to the big battery drain I'm having? An older AOSP build (end of march with another 3.10 kernel branch) does not have this kswapd0 issue and has a far better battery life.
PID PR CPU% S #THR VSS RSS PCY UID Name
79 1 50% R 1 0K 0K fg root kswapd0
This post reports similar issues but is of an older kernel (so probably not related): http://forum.xda-developers.com/general/rooting-roms/fix-kswapd0-cpu-usage-problem-t2845239 Is there a parameter somewhere not set right?I even tried compiling a kernel with CONFIG_SWAP=n but kswapd0 is still there :-(

(I removed "BOARD_KERNEL_CMDLINE += mem=883M" from BoardConfig.mk) The battery life seems better now, but still not as good when comparing with the march build. best regards

High CPU usage when downloading Files

Hi there,
i noticed somethign strage when I download file off the internet or intranet. As soon as my download speed surpasses 1MB/s the CPU usage increases. To be exact the process kernel_task.
For example:
2,5 MB/s -> ~30%
10 MB/s -> ~60-70%
10+ MB/s -> ~80%
This is really annoying and I have now clue how to fix this. The Harddrive is a SAMSUNG HM320JI with a Journaled HFS+ partition. No Virus Scanner or anything. Also just reinstalled Snow Leopard yesterday.
Hope someone can give me some useful information how to fix this.

Hiya,
could it have something to do with the write speed/ cache/ram? On a "slow" disk, or one that is nearly full or one that is partitioned, it will take a great deal more ram and cache to "digest" the faster download and write it onto disk. I tend to do downloads to a separate drive. Have you got one? and can you repeat the high CPU usage when downloading / saving to the external drive? I note your drive might have 5,400 rpm, with "just" 8mB cache and 320 GB (quite a few SATA's have 7,200 rpm and 32 mB cache).
NB: If anything, I found SL more efficient, especially on my 4 year old Macbook, which is running much faster and has got more responsive after installation of (full version of) SL.

High CPU usage when playing flv files with flash

As more and more FLV videos are moving to HD, I'm noticing
high CPU usage and lots of dropped frames when playing FLV video in
web browser with Flash 10. This is true even if the video isn't
full screen. I've tried a variety of browsers (Firefox, I.E.,
Chrome) and the problem occurs on all of them so it's pretty clear
it's a limitation in Flash.
Now my PC isn't high end (it has a Pentium M 1.86 GHz
processor), but I can take those same FLV files and load them in
something like Media Player Classic or Windows Media Player (when
using ffdshow) and play the FLV files full screen with little or no
drop in frames and an acceptable CPU rate.
This is especially annoying on sites like YouTube where I
actually have to save the video and play it back in something other
than Flash to have it play back at an acceptable rate. This doesn't
work for other sites like Amazon.
Why is the CPU usage so high when decoding and displaying
videos when compared to other media players?

I've been doing research about this excessively high CPU usage problem (100%!) for weeks because I have also experienced it with my vista home premium laptop. Just recently, I have finally found the solution. The problem is not your browser or your OS or your pc's memory. The problem is caused by authorization for flash player.
Read the link (posted below) carefully and follow the steps accordingly. If you have already done steps 1 through 6 with your computer, you can go straight to step 7.

High CPU usage when editing large MXML files

I am using Flash Builder 4.5 Plug-in on OSX. When I have a large MXML file open, Eclipse will consume 100% of the CPU as long as that file is open, even if I am not doing anything. If I close that editor the CPU usage goes back down. I've seen this in Flash Builder standalone as well as the plugin. Is there a workaround to stop this CPU usage problem?
Thanks

Database file + high cpu usage

this has only started happening since i formatted and reinstalled windows. i have tried using both itunes 6.0.2.23 and 6.0.4.2 and both have the same problem.
my music library contains 5088 songs, i have tried deleting heaps down to around 3400 and problem is still there (ie i have eliminated number of songs as a factor cause before formatting i had more than 3400 but less than 5088)
when i play a song in itunes after about 5 seconds my cpu usage will jump to 100% this is on the "system" process, itunes itself uses around 2-5%. i was watching the itunes music folder though, and what it is doing is creating a new temp file (of 7.27mb) then renaming it to replace the current "itunes music library.xml" file. as soon as the xml file is replaced (takes about 10 seconds) cpu usage returns to normal.
this exact same thing happens when i quit itunes, although it takes roughly 20 seconds.
i have tried deleting all files in the itunes music folder apart from the base database file, that did nothing.
i tried removing the entire folder and letting it create a new blank library, then added just 1 album, and it worked perfectly. i also noticed that on my original library most but not all AAC encoded files did not cause the cpu spike, all mp3s did.
i tried creating an entire blank library and adding all my music back in, it still did high cpu usage so i would assume my current database is not corrupted.
does anyone know a solution to this? how to stop it recreating the xml file with every song played. the only thing important to me is saving my playcounts, so any solution which does not require losing them would be appreciated.
also yes i have tried completely uninstalling itunes, for both of the versions mentioned above, also tried updating over the top of the current installation, problem occurs everytime.
i am running service pack 2, all current windows updates installed, no spyware, no viruses.
thanks.

It may be iTunes, but it probably is not. iTunes is just affected by a conflict with another program (possibly).
Do you have a spy sweeper/virus scanner/etc. that periodically scans your PC memory? If so, then that is what may be interacting with iTunes.
You should list the iTunes Folders as part of the exclusions within your Virus Scanners, and other Security software.
BTW: I have a Library with over 13,000 song references. I do not see the same CPU spikes when playing music. It's not the size of the database - not at your current level.

MSI KT6 Delta LSR SATA to PATA High CPU Usage Problem

Well recently I've switch to my one of my other motherboards on my network to a MSI KT6 Delta LSR, it was working fine after a reformat, but I notice a few problems and that is 100% cpu usage for SATA to PATA, and vice versa, which seems really crazy. Then my network card performance is ISDN speed sluggish, and I tested my line to be working 100% with another mobo. But when I put another NIC on the same mobo it suffers the same speed problems.
Any suggestions? The rig is specs:

I recently installed 160g Seagate barracuda 7200.7 drive on SATA port. (I enabled the Bios using Auto) I have a P4I865pea-6al mother board, with two PATA drives . When copying files between the PATA drives on ide ports, to or from, the SATA drive, I notice the CPU usage goes up to 100%, but when copying files from one ide drive (the PATA drives) to another the CPU usage is very low.
Is there a bios setting that will allow me to copy files from the SATA drive to the Pata drives using a small amount of CPU power, found when just copying between the Primary and Secondary IDE drives? I am using Adobe premiere pro, which uses a lot of CPU power, and the high CPU usage of the SATA drive crashes this program? Any help would be appreciated
