On the same hardware platform, by just moving from 32 bit Linux to 64 bit Linux, will I have better performance with operation memory coping. Specifically, will function memcpy run faster? Please note that nothing changes on hardware side, I just want to use 64 bit Linux if memcpy performs better.

My usb stick will not allow me to easily copy and paste files on to it, or delete them once I no longer want them on the drive. Its owner is root. How can I change the owner? At the moment it is loading as a stylesheet in media/usb0.
The file is transferring at a very low speed. 74mb in 4 minutes
I suspect I will do better if I set up the drive via fstab. What entry should I put in fstab for a USB stick drive?
I have some playlist I want to keep the songorder, but I have the files in another file-structure.( I have the songs ordered in folder by artist and album, cos all songs are note tagged correctly or in the same way.)I want to use the playlist with the songs in copied to an another plays, for instance an usb-stick.Is there an application who fix mass change of all links to the songs?
for instance I have in m3u-files:
#EXTM3U
#EXTINF:268,Salt Fare North Sea[code]....
Or Is there a way in Amarok or another music-player that can make a copy of the playlists song order and use it with new links on a usb-memory? I don't now how sync to media-player and such things work.

There is one little thing annoying me in man pages. When I search for text using '/' command the line where the text is found is positioned at the top of the screen. I find it inconvenient because when I search for text I want to see it in the context which also includes the a couple of lines before the found text.Is there a way to tell the man pager not to scroll the screen all the way to the top during search?

View 2 Replies View RelatedBasically I'm wondering if there is any way to lighten Gnome and Ubuntu I would like to keep Gnome if possible. I am a pretty experienced linux (or for you hardcore GNU fans GNU/Linux) user having used it for almost 4 years and I just built my Arch system but have found that alot of the functionality that I've come to love about ubuntu isn't in the default Gnome package but that Ubuntu's Gnome is heavily modified so I want to switch back but do to my lack of modern hardware I can't run Ubuntu as smoothly as I want.
Below is my current hardware.
Code:
Intel Pentium III 733mhz
512mb of ram
8gb Hard Drive
and a Dvd Drive
Nvidia Geforce 6600 265mb pci gpu
100 watt power supply
I am also a Developer so I know I can compile the Kernel my self and remove some not needed junk and optimize it. But I was wondering are there some Highly intensive processes that don't really need to be running? The only thing I would be using Ubuntu for is Web Browsing, Coding, Gimp, Text Processing and probably Music; thats really all I need I don't do much else besides that.
tl;dr:
Basically all I'm trying to do is lighten Ubuntu and Gnome without putting 3 days worth of work into it.
I am running a ubuntu desktop machine as a server and use VNC from my windows machine to login via a LAN to the ubuntu machine. The login session is very sluggish and frustrating. I installed gnome-rdp to see if it would be better but I don't know how it works or what to do and if there is something else I can do to improve the performance. I have 3 gig of ram and the server is a dual celeron machine

I found the fonts sometimes a little thin. I've heard of compiling freetype with bytecode interpreter enabled. Is this necessary on Squeeze? If this would make an improvement what would I need to do?

I have got a Radeon X800XL built in my computer. I was able to play Quake 4 in high details once, so I guess my PC is quite fast. Anyway, I have trouble playing Anno 1503 and SuperTuxKart (sic!). While Anno 1503 is fairly unplayable, SuperTuxKart has got around 30 to 90 fps, depending on the situation. In my opinion, that's way to less.
My question is: How could I improve the 3d performance, to be able to play such legacy games as Anno 1503? Therefor I'll give you some information about my configuration and what I tried so far.
I run Ubuntu 10.04. That means, the driver provided by AMD/ATI (fglrx) does not work anymore. My Ubuntu is up to date.
I set the kind of graphics card and the graphics ram in the Registry of Wine. Disabling the compiz-fusion-effects does not improve the situation however.
I disabled KMS. That gave an amazing performance boost, but still not enough. I am still experiencing performance troubles like being unable to play Anno 1503, and some others.
I also created a Xorg.conf, trying to tweak some settings, but that does not improve the performance much. The config file is attached below.
How to improve or accelerate the 3d-performance. Maybe there is an beta-driver or some xorg-settings I did not find?

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
we found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

View 2 Replies View RelatedI am monitoring physical memory in a server I administer, and my hardware provider told me they had increased physical memory size to 4Gb... However, using several tools (free -m; top; dmesg | grep Memory; grep MemTotal /proc/meminfo I discovered that I actually have 3Gb, not 4... But, my doubt comes from the fact that dmesg | grem Memory tells me I have 3103396k/4194304k available The first number is effectively 3Gb, but the second one, is 4! so, why I am looking at this two different numbers?

I was using centos for my business applications and now I am trying to work only with opensuse and install my other oprerating systems in it. I was always using vmware , but I decided to try another virtualization technologies other than vmware for testing , I searched the internet and found many other like virtualbox , kvm , xen. I concluded from my search that xen and kvm will be the faster type , I decided to test them, I choose xen, it is better than kvm. I installed opensuse 11.4 and installed xen hypervisor deployed two VMs windows xp and centos 4.8 , they are runing quite good but I have some questions:
1 : Isn't there anyway to improve graphics performance in xen guest , or change the video card memory or type ?
2 : Isn't there any way to copy and paste between the host and guest ?
3 : Isn't there any free application like vmware tools or virtualbox guest tools for xen ?
4 : I use these VMs to install some applications for my geophysics work which requires good graphic performance in the vm , also I don't them to be sluggish sometimes , which is better for that vmware or xen ?
