I mount a BD-RE in Debian Jessie to write about 20GB of data. But the writing speed is terrible slow. I get a Speed of 250kb/sec.
Are there any options to increase the speed of writing? I don't use packet writing and no wodim, no growisofs, nothing. I just mounted the disk and I use mc (Midnight commander) to copy the data.
I have just formated and did a fresh install to start all over. I installed Ubuntu 9.1 and everything went fine but the network. The computer serve as a NAS and MediaPlayer. When getting a file from the server, I get a speed of 40-60mb/sec, which are good for a Gigabit network. When I try to put a file in, the speed can't pass more than 1mb/sec and often stop.
Here's the network info:
Code:
vric@XBMC:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:24:8c:a1:eb:55
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::224:8cff:fea1:eb55/64 Scope:Link

[code]...
Edit: Looks like it's a Gigabit Problem. I connected the Ubuntu box to my Linksys router which is 10/100 and everything is MUCH faster.
I have a 500gB USB drive connected to my laptop for backups and filestorage. But I can't get it to play nice with Midnight Commander. My transfer speeds max ut at 2MB/s wich is painfully slow when moving large files such as movies. Worker FM transfers the same files to the same drive much MUCH faster (not sure by how much, though). This leads me to the conclusion that the problem lies with MC.

I've tried with different cables on the server, no luck. Also note that the laptop gets full speed to speedtest.net as per my internet subscription (75/75 gbit fiber), so the laptop can be ruled out as a problem since it gets more than 75X performance to the internet compared to the local server.
The main purpose of this server is to be a virtualbox host. I've set up one guest system and ran iperf between the host/guest (bridged network). It gives better numbers, still the host -> guest direction is much slower than it should be:

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab
When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s
But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.
I am developing a GPS driver which is connected over a high speed UART. The driver of the high speed UART is available and it creates a device node /dev/ttyHS0. Now using the device node, I guess, I will be able to read/write from/to the GPS chip from user space but my aim is to write a GPS driver in the kernel space which would communicate with the high speed UART driver. After some initial study, I think I can either write a line discipline driver or a serio to communicate with the GPS chip firmware through high speed UART driver.

I'm on a Dell Inspiron 6000. I installed i8kutils and it works. Fan speed reduces CPU temp from 50C to 44C. A start-up script invokes the i8k module: $ udo /usr/sbin/modprobe i8k force=1 which creates /proc/i8k. The man page for i8kctl is straightforward: a few simple commands to read info from the aforementioned file.So. I know nothing about writing even basic bash scripts. I gave it a go here but I know this is way wrong. Would anyone like to help a guy out? This is my starting point (don't laugh):

This is a curiosity of mine, and I expect a technical answer, if someone knows it. Why the systems become so irresponsive when doing hard-disk input and output? This happens even if writing is done to a secondary disk where neither the system or the swap are stored.
View 7 Replies View RelatedI have a USB hub on my desk, and also a multi-card reader in the front-panel of the computer (connected to a USB PCI card).
I have found that when I write files to a USB "thumb" drive plugged into the USB hub, or to a card in the multi-card reader (I have tried SD, SDHC, CompactFlash and MMC) the file is written quickly. The progress bar that appears on the screen goes to almost 100%, but then stops...
If I try to unmount the filesystem (either umount on the command line, or MB3 and eject or unmount option) I get a message that the device is busy. Sometimes, this stays busy for three minutes.
The filesystems on these cards are almost always FAT32; they are for digital cameras, media players, or are for exchanging files between home and office (where I use WinXP).
Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.
I've been, for some years, an happy user of Highpoint HPT374 based RAID cards, using RAID 5 with decent performances (constantly around 90 MB/sec in read, and 60 MB/sec in write ). Old Athlon mobo , with 2.6.8 kernel. Now the mobo is dead, so I've got an Asrock A330GC (dual proc with 4giga ram), installed Debian with kernel 2.6.26 and moved the controller and disks , and the performances have dropped to a painful 9 MB/sec in write, measured with dd of a huge file (interrupted with kill -USR1 [pidof dd]).
Read performances are still around 90MB/sec, using hdparm -t , repeated many times , figures are constantly around 90MB/sec. I suspect some libata issue , in old kernel the raid was seen as hdb, now is sdb, some driver(s) of the PATA disks may be responsible. I've used the driver, from Highpoint v2.19 , the latest driver is broken (causes kernel oops during format of raid), I've informed Highpoint.

I am running Ubuntu 10.04 from a USB key (16GB). Overall I'm pretty fine with it but there are a few problems I am having. It seems to be very slow. In particular, Firefox and Pidgin freeze every now and then, before becoming active again. The same thing also happens for other applications such as Rhythmbox, Gedit, and the terminal. Additionally my start up and shut down times are horrible (worse than when I use Vista and Ubuntu 8.04). I was wondering if there is something with my install or if this is all due to the fact that I am running from a USB. I don't think it's the USB since I ran 8.04 from a USB HDD (55GB) and didn't have any problems with speed.

I have been trying out Ubuntu One for the past couple of days but find it to be incredibly slow. At first i had put a folder will a large amount of images in the ubuntu one folder. The total size of it was 35Mb, after over 26 hours only 11,5Mb of that had been uploaded.
After looking around some on these forums i saw several comments about it being slow when it is a large amount of files, no matter if the filesize is small or large. I decided to try it out with a larger single file. I erased everything that was in the previous share and then put my testfile of 350Mb in the Ubuntu One folder.
After two hours of waiting i could still not see it on the U1 website so i decided to see how long it would take with dropbox and put a copy of that file in my dropbox folder as well. The file was uploaded correctly to dropbox in just a couple of minutes but it has still not been uploaded to the U1 website even though it has been 4-5 hours since i first put it in my U1 folder.
I need to transcript some recordings to a friend of mine. I woule like to have the sound playing slower than usual. Is it possibe on any Ubuntu (L. Lynx) anyway? How?
View 7 Replies View RelatedDoes anyone know if the Yum fastestmirror plugin only makes decisions based on latency to pick the best host or does it measure bandwidth? On my laptop for the last few weeks I've been getting super slow yum updates (3.5kB/sec), when I force it to use the baseurl it runs as fast as I'd expect (160+KB/sec).
So the fastestmirror plugin doesn't seem to work unless maybe it's measuring latency as fast but the actual download speed is slow. If so, fastestmirror plugin should really take both into account.
I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).

I'm trying to transfer some files to my USB stick, and it's transferring at the most pitiful rate, around 200-400kb/s, occasionally shooting up to 1MB/s, but not for more than a few seconds.

Sometimes too, the transfer just stops all together. It just... doesn't transfer for a while, then it'll go back to 400kb/s etc, then it'll stop again for a minute.
When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk.

We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.
I am currently using fedora 12. My question is why is the speed for my yum and rpm are very slow. Something like Flash Player 10 couldn't even load after being installed. If I downloaded the rpm, the speed is like normal but if I yum it. The ESA took like >1,000,000 sec..or whatever..The point is it does seem like something has happened to my yum/rpm function. I can download and surf the web as usual. I just can't get any add-on such as the Flash Player 10. I can only use the basic already provided by Fedora.
I tried:
su -
yum clean all
rpm --rebuilddb
yum update
but I am still unsure what type of RPM issue I am facing.
