When I copy a file(13Megs) from /home/ to /tmp/, sync takes almost 2 minutes. When I copy the same file to /usr/local/, sync returns almost right away. Both filesystems are ext3 and are on the same harddrive. When sync is running, the harddrive light stays on but I don't hear it doing anything. dmesg doesn't show any errors either. Below is the `time` output for each command. If you need anymore information let me know.. The CPU is a PIII866 with 512MB RAM. $ uname -a Linux dev-01 2.4.19-pre10-ac2 #3 Sun Jun 30 18:56:04 EDT 2002 i686 unknown $ hdparm /dev/hda /dev/hda: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 1868/255/63, sectors = 30015216, start = 0 busstate = 1 (on) $ cat /proc/mounts /dev/hda1 / ext3 rw,noatime 0 0 /dev/hda2 /home ext3 rw,noatime 0 0 /dev/hda3 /usr ext3 rw,noatime 0 0 $ df -h Filesystem Size Used Avail Use% Mounted on /dev/hda1 387M 162M 205M 45% / /dev/hda2 3.4G 2.1G 1.1G 65% /home /dev/hda3 10G 6.3G 3.4G 65% /usr $ cat /proc/ide/via ----------VIA BusMastering IDE Configuration---------------- Driver Version: 3.34 South Bridge: VIA vt82c686b Revision: ISA 0x40 IDE 0x6 Highest DMA rate: UDMA100 BM-DMA base: 0xc000 PCI clock: 33.3MHz Master Read Cycle IRDY: 0ws Master Write Cycle IRDY: 0ws BM IDE Status Register Read Retry: yes Max DRDY Pulse Width: No limit -----------------------Primary IDE-------Secondary IDE------ Read DMA FIFO flush: yes yes End Sector FIFO flush: no no Prefetch Buffer: no no Post Write Buffer: no no Enabled: yes yes Simplex only: no no Cable Type: 80w 40w -------------------drive0----drive1----drive2----drive3----- Transfer Mode: UDMA PIO PIO PIO Address Setup: 30ns 120ns 30ns 120ns Cmd Active: 90ns 90ns 90ns 90ns Cmd Recovery: 30ns 30ns 30ns 30ns Data Active: 90ns 330ns 90ns 330ns Data Recovery: 30ns 270ns 30ns 270ns Cycle Time: 30ns 600ns 120ns 600ns Transfer Rate: 66.6MB/s 3.3MB/s 16.6MB/s 3.3MB/s $ ls -al mozilla-i686-pc-linux-gnu-sea.tar.gz -rw-rw-r-- 1 khromy khromy 13M Jul 2 07:42 mozilla-i686-pc-linux-gnu-sea.tar.gz * time output when I copy to /usr/local $ time cp mozilla-i686-pc-linux-gnu-sea.tar.gz /usr/local/ 0.00user 0.19system 0:00.18elapsed 102%CPU (0avgtext+0avgdata 0maxresident)k $ time sync 0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdata 0maxresident)k $ time rm /usr/local/mozilla-i686-pc-linux-gnu-sea.tar.gz 0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdata 0maxresident)k * time output when I copy to /tmp $ time cp mozilla-i686-pc-linux-gnu-sea.tar.gz /tmp/ 0.01user 0.24system 0:00.25elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k $ time sync 0.00user 0.05system 1:39.14elapsed 0%CPU (0avgtext+0avgdata 0maxresident)k $ time rm /tmp/mozilla-i686-pc-linux-gnu-sea.tar.gz 0.00user 0.05system 0:00.05elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k -- L1: khromy ;khromy(at)lnuxlab.ath.cx
