Hi: I found there is some problem with SLE problem: each time I am copying large files into removable disk or I am tar some big files, the whole system became very slow: almost all the program and windows stuck there… No matter how well (I get a 24 CPU (3.6 GHZ), 32 GB memory workstation) is my CPU or memory is, the problem always happen. I don’t install beagle and compiz in my system. How to solve this problem ?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Exactly. The main bottleneck of almost every system in the world is I/O. When your system is busy using the disk, especially when it is reading from it (to get the files) and writing to it (to create the tar) at the same time your system will seem slow because of that bottleneck no matter how much RAM or how many CPUs you have. When you’re sitting at a stoplight (waiting on something else) it doesn’t matter how fast your car goes or how much your pickup can carry; the stop light is going to keep you from getting anything done.

Anyway, maybe using ionice to reschedule the activity, watching the output of the command vmstat 2 may show info. What is the exact command your running? Are you running tar as one operation then copying, or running tar straight to the device? With the device plugged in can you post the output from it’s dev number eg; ```auto hdparm -t /dev/sda ``` Are you using tar on windows? Remember tar is i/o bound it does a read or a write then waits. You need to look at something that will use all that processing power… pbzip2 for example.

The only time I’ve seen behaviour like you describe was about five years ago no a machine that was old enough to have a PATA harddisk and DMA had somehow been disabled. The system was hopelessly unresponsive when there was any significant disk access going on. Given the specs you mentioned I very much doubt you have a PATA harddisk though. What does this give you? ## Code: ## $ for i in {1..5};do hdparm -t /dev/sda;done I get figures of around 80 MB/sec. This sounds like an issue that could be very difficult to diagnose. Have you considered raising a Service Request with Novell?

Honey, I don’t tar or untar files all the time in my computer. Of course I can edit posts. Here is the output of the command: /dev/sda: Timing buffered disk reads: 304 MB in 3.00 seconds = 101.28 MB/sec /dev/sda: Timing buffered disk reads: 250 MB in 3.00 seconds = 83.32 MB/sec /dev/sda: Timing buffered disk reads: 306 MB in 3.01 seconds = 101.80 MB/sec /dev/sda: Timing buffered disk reads: 306 MB in 3.01 seconds = 101.81 MB/sec /dev/sda: Timing buffered disk reads: 242 MB in 3.00 seconds = 80.63 MB/sec ## – albumns albumns’s Profile: [http://forums.novell.com/member.php?userid=48883](http://forums.novell.com/member.php?userid=48883) View this thread: [http://forums.novell.com/showthread.php?t=444967](http://forums.novell.com/showthread.php?t=444967) ---

Hi, i red all replies and have some idea 😉 Are you using tar operation on removable or on physical disk? With file system are you using? Do you anytime check the value “%wa = waiting operation” in the top during tar or coping? If is bigger then “%id” there is possible mistake in the disk partitioning. I had these problem with 4096-Byte Sector Hard Drives, and it sound very similar. 😉 Witch OS create the partitions? If windows, that can be problem. 😉 ## – Honzik friedl\_jan’s Profile: [http://forums.novell.com/member.php?userid=56174](http://forums.novell.com/member.php?userid=56174) View this thread: [http://forums.novell.com/showthread.php?t=444967](http://forums.novell.com/showthread.php?t=444967) ---

I do the tar operation in physical disk and I use ext3 which is the same with removable disk. someone suggest me to use this command to check something, but I don’t know what’s that: sudo /sbin/hdparm -i /dev/sda /dev/sda: Model=ST9500420AS, FwRev=D005SDM1, SerialNo=5VJ5J20R Config={ HardSect NotMFM HdSw\>15uSec Fixed DTR\>10Mbs RotSpdTol\>.5% } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=16384kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=976773168 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 \*udma6 AdvancedPM=yes: unknown setting WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-4,5,6,7 - signifies the current active mode ## – albumns albumns’s Profile: [http://forums.novell.com/member.php?userid=48883](http://forums.novell.com/member.php?userid=48883) View this thread: [http://forums.novell.com/showthread.php?t=444967](http://forums.novell.com/showthread.php?t=444967) ---
