Re: USB Hard Drive Transfer Rate Testing! Come Get Some!
i think i found some tricks. with these i have stable 11.5 MB/s download transfer speed with vsftpd and with samba 10MB/s on 1.5.8 while transmission-daemon not under load off course .
echo noop > /sys/block/sda/queue/scheduler
echo 1024 > /sys/block/sda/device/max_sectors
echo 1024 > /sys/block/sda/queue/nr_requests
or in sysctl.conf
/sys/block/sda/queue/scheduler=noop
/sys/block/sda/device/max_sectors=1024
/sys/block/sda/queue/nr_requests raises=1024
echo noop > /sys/block/sda/queue/scheduler
echo 1024 > /sys/block/sda/device/max_sectors
echo 1024 > /sys/block/sda/queue/nr_requests
or in sysctl.conf
/sys/block/sda/queue/scheduler=noop
/sys/block/sda/device/max_sectors=1024
/sys/block/sda/queue/nr_requests raises=1024

Not sure what is slowing you down. Maybe the newer stuff uses more cpu as you see 81% sys...
11 seems normal, I got that with openwrt. Never used usb on gargoyle... by then I made my own NAS/CableTV pc.
You might want to disable bwmon (bandwith monitor). It sucks up cpu, but doesn't show up as an application in top/htop (like it's part of the kernel?). Also try the settings in the post before you....

Code: Select all
cd /etc/init.d
./bwmon_gargoyle stop
./bwmon_gargoyle disable
chmod -x bwmon_gargoyle

Yeah like you said, i was already disabled bwmon and webmon services because i'm not using them.Thanks for tip anyway!robnitro wrote:Not sure what is slowing you down. Maybe the newer stuff uses more cpu as you see 81% sys...

Also what helped me was to use noatime to mount the drive. Not sure how the gargoyle openwrt does it. I had a mount script, so I put in -o noatime... fstab is similar but I couldn't get it to work then with the usb hotplug.
Noatime is much like the tweak people use for windows NTFS- disable last access stamp.

NAS was significantly faster than ext3
The existing is difficult for me, Im noodle.

Another tweak for file reads :
in sysctl
/sys/block/sda/queue/read_ahead_kb=1536
or
echo 1536 > /sys/block/sda/queue/read_ahead_kb
Now with vsftpd got 12.20MB/s download file from usb hdd, 12.02MB/s upload file to usb hdd.
I think these are limits of 1043nd's cpu.
My last mount line :
in sysctl
/sys/block/sda/queue/read_ahead_kb=1536
or
echo 1536 > /sys/block/sda/queue/read_ahead_kb
Now with vsftpd got 12.20MB/s download file from usb hdd, 12.02MB/s upload file to usb hdd.
I think these are limits of 1043nd's cpu.
My last mount line :
Code: Select all
mount -t ext4 -o rw,noatime,nodiratime,data=writeback,barrier=0,nobh /dev/sda2 /mnt
Re: USB Hard Drive Transfer Rate Testing! Come Get Some!
In order to get mount options like noatime going on every mount, without breaking gargoyle's automount, I just edited the appropriate filesystem in /etc/init.d/usb_mount
In my case, NTFS, since I want the drive to work without fuss on windows boxes...

Hi, I have a seagate HHD of 1TB while trasferring the data from HDD to my laptop it provide data transfer rate of 25 MB , but in vice-versa case it proveide only 15 MB data transfer rate , is this a problem of the my RAM or of my HDD.robnitro wrote:A tweak I posted on the openwrt forum helped a bit:
echo 1024 > /sys/block/sda/device/max_sectors
OR
add
/sys/block/sda/device/max_sectors=1024 to /etc/sysctl.conf file and then run sysctl -p or reboot.

Re: USB Hard Drive Transfer Rate Testing! Come Get Some!
thanx ..I will test for ext3, ext4 and xfs using Transcend USB Flash drive in my computer.
xfs was fastest on reading, ext4 - best for writing

Oh. Yes, I think so, let's make friends.
