Ubuntu :: Moving Tmp To RAM - Performance Increase
Jul 15, 2010
I've found this page: [URL]
I've followed several suggestions on my system and overall performance is better.
My question is related to the following:
Quote:
OPTIMIZATIONS NOT RELATED TO STARTUP
Move your temporary files /tmp folder to your RAM if you have loads of memory. This will also provide you greater privacy. Edit /etc/fstab and add the following line to it
tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0
Is this not normally implemented since some users don't have a lot of RAM?
Also, would it make that much difference if the system didn't have a lot of RAM to work with?

Is there anything that can be done to increase video streaming performance?The general impression I got is that it's mainly an adobe problem and not much can be done, though currently streaming is nearly unwatchable. When I switch from full screen to normal size many of the players freeze, ..... HD is unwatchable etc.

Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

I like the buttons on the left. I'm running 10.04 & I know how to move them. The problem is that changing themes will move them back right. OK, if the new theme has them on the right that's OK. But going back to the other theme doesn't change them back. They don't seem to be controlled by the theme, or I'm just not doing it right.

I have limited experience in terminal, but let me first explain what I am trying to do to see if there is some easier way to do it. Basically I want to change the skin in aMSN. I downloaded the new skin but am unable to unzip or move it without /root permissions. I don't know how to acquire this without being in terminal. So I figured there had to be some way to go into the terminal and use it to move the unzipped folder from the desktop to the aMSN skins folder.

I used to have Windows on my laptop, until I got the blue screen, so I just installed ubuntu. Well everything was ALOT louder on Windows, and I was wondering if there was a way to increase the maximum volume. I have to turn the volume almost all the way up to watch a movie. On Windows 1/4 volume was plenty. I searched, but alot of the answers I saw were that it was hardware limitations, which cant be the case, since it was a ton louder on Windows

I've a laptop from 2001 with 512MB of RAM, and I was running Windows XP, and the laptop wasn't coping very well with the huge demands of the applications of today. It was only yesterday I installed Ubuntu alongside XP and I was surprised to see how fast everything was!
The only thing that's bugging me a bit is the screen. Some parts of the desktop shows some banding where there is meant to be a gradient, probably telling me to increase the color depth. Is there a way in Karmic Koala to change the color depth? I tried using sudo gedit /etc/X11/xorg.conf but when the editor shows up with the setting file, it's empty.

I have 4 primary partitions on my hard drive. One of these partitions has been divided into 3 logical partitions with some free space left over. The order is this: "swap", "/", "/home", and about 80GB of unallocated space. I want to incorporate that unallocated space into the home partition. I tried this by booting a live CD and starting GParted but it didn't give me the option to increase the size of my home partition or the primary partition as a whole. The only thing it would let me do is decrease the size of my home partition.

Default Ubuntu drivers work fine, but wanted to take advantage of what the new drivers had to offer.
Using Ubuntu 10.10.
Installed latest catalyst drivers vers 11.3 My board has a inbuilt ATI Radeon HD 4250
i installed originally via admin -> additional drivers, but my desktop has shrunk about an inch around the edges (splash screen also changed)
I'm using a Panasonic Plasma Screen (XBMC HTPC) vis HDMI.
Catalyst mentions the Panasonic in Display Manager, but also mentions a Projector (1), which is also the Panasonic TV .
Resolution is set ate 1920 x 1080 and refresh 50 Hz.
I then reinstalled the ATI drivers as per [URL] , but no change (and lost screen coming out of XBMC).
I also installed the splash page fix here [URL] so now at least it looks pretty.
fglrxinfo gives me
Code:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4250
OpenGL version string: 3.3.10600 Compatibility Profile Context
how I can increase the size of my desktop?

Finally i have installed ubuntu 10.10 on my home PC. Its working so so good i cant really imagine :-). At the time of partition due to my immaturity, i selected the size of '/' to be 10 Gb. Now i want to increase it without reinstalling ubuntu. Is there any safe way of doing it ? i did some research and came to know that Gparted might be of some help, but i will really be grateful if any of you can guide me.
the use of livecd for example, can i use liveusb instead ? i was thinking of making liveusb of centos 5.5.
Currently i have 3 partitions
'/' 10 GB
'/boot' 99 MB
'Date' 50 GB
on rest, its my windows xp.

I can't increase my screen resolution to higher than 800x600. In Windows I have a 1024x768 resolution. This is my xorg.conf file
Code:
# xorg.conf (X.Org X Window System server configuration file)

Last week my ping was 45 this week its 80. I've checked it on three different computers, and reset my router. I called verizon (my subpar isp) they run a few test, say every things fine. I recheck my ping, its back to 45 but only last 5 mins after they check it, then it goes back to 80. I'm always having problems with them, but every time I call them the problems "just so happen" to go away while their helping me.
Anyway, my question is... Is there anyway for me to increase my ping/speed without upgrading my internet? I have 3.5 upload, .75 upload, and a Westell model 327w. I know this is a general question and not really linux related but I thought I would try this forum first since its always so helpful. I have googled this subject but I only find windows related stuff that pertains only to the programs running on the machine. They suggest things like "dont download when you want high ping" and "temporarily turn off seeding for your torrents" It is most important in windows for me though, I like to play games and a difference of 50 and 110 ping does make a difference. Of course, everything seems slower, like streaming movies and stuff.

Ubuntu, in its most recent version (9.10) has stopped to support certain webcams that it previously supported with just plug-and-play simplicity. After many searches on the web, I could somehow managed to make my old webcam (Logitech QuickCam Traveler) work. Skype couldn't see it, but adding the command bash -c 'export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so; skype' to the launcher, worked the miracle.
Whatever, the image was very dark, and in a new web search I found a solution [url] As stated there, I opened the Terminal and entered:
Code:
All is OK, brightness gets up, I can finally see my face (not a great view, but I somehow got away with it) in Skype's test, but I need that change to be PERMANENT, so every time my parents open Skype (it's my parents' computer) they won't have to mess with Terminal (they're 69 and 72 years old, it's their first computer, so I CAN NOT expect them to use Terminal, they just want to open Skype and use it, as they did when they used Windows (until two weeks ago, when I finally convinced them to switch).

I have installed ubuntu on my second hd, the size of is 500 GB.The live Ubuntu cd installation have used only 250 GB, the rest remains as NTFS system. And now I do need more space on my home folder, I would like to convert the 250 GB NTFS to Linux system and add it to my home folder. But I don't know how. I have looked at Disk Utilities, I have not found this possibility.
