Ubuntu8.04 Series 6-software optimization article reproduced in: Jia Junyuan http://luckiss.blogcn.com

The system needs to be optimized, and the software also needs to be optimized using ipv_^ 1. Firefox's ultimate Optimization of Firefox 3.0 is currently the best in browsers, but after optimization, you will find it faster and easier to use! Enter "about: config" in the URL bar of Firefox to enter the configuration page, and then search for the following key items. If you cannot find these key items, create your own and create a Boolean for "bool, an integer is an integer, and a string is created to change the network. HTTP. pipelining is true network. HTTP. pipelining. firstrequest true network. HTTP. proxy. pipelining true network. HTTP. pipelining. maxrequests is 48 nglayout. ititialpaint. delay 0 network. HTTP. max-connections 48 network.

For details, see article 16th optimization methods in ubuntu8.04 Series II-system optimization. After modification, restart Firefox 2. To optimize amule, open amule -- settings -- General, and change the nickname to [TLF] [CHN] [verycd] [Cyndi] [twed2k] yourname to enable amule -- settings -- connection, make the following settings: Empty block allocation: 1kb/s absolute upper limit: 500 Max connections: 7500 open amule -- settings -- server -- list and add the following server list: http://www.emule.org.cn/server.met http://www.srv1000.com/x1/server.met http://emule.945.cn/server.met http://www.edk-files.com/x1/server.met http://corpo.free.fr/server.met can copy all the servers in the config directory of your eMule directory under windows. met. go to the amule directory, amule The default path of is ~ /. Amule/open networks -- Kad, and then replace the original address with this: http://www.emule-inside.net/nodes.dat and then click the button on the left to download the link when using amule if firewall is not enabled, faster amule and Firefox Association: Enter about: config in Firefox and create the following two variables: 1. create a Boolean network. protocol-handler.external.ed2k, value true, indicating the protocol that processes ed2k 2. create a network of the string type. protocol-handler.app.ed2k, value:/usr/bin/ed2k, specify the program for processing ed2k protocol is/usr/bin/ed2k 3. OpenOffice startup Speed Optimization 1 ). open OpenOffice writer and choose tools> Options> memory: 2 from the menu ). modify: undo command-> Number of steps: 20 3 ). modify: graphic buffer-> used for OpenOffice: 128 M, memory of each object: 20 M 4 ). activation: system bar Quick Start

• Deselect 'use Java runtime environment' on the Java option page to set the input method.

4. Adobe Flash for Firefox Optimization Problem for 32-bit Ubuntu, Adobe Flash is not a problem. When using Firefox, FF will automatically remind you to download the flash plug-in, the installation process will be smooth, but for 64-bit Ubuntu, flash installation will be a little troublesome, please follow the steps below: First, you must ensure that the 32-bit compatibility package has been installed: sudo apt-Get install ia32-libs ia32-libs-gtk linux32 lib32asound2 and then install the following software: sudo apt-Get install nspluginwrapper gsfonts-x11 8.04 default browser is firefox3.0 beta5, when Firefox is started, it will prompt you to download the flash plug-in. Press the button and the following will appear: select to install Adobe Flash Player, and then choose to install flashplugin-no. Nfree: After the installation is complete, restart Firefox to view the Flash. Open the tool-add-ones in the browser and you will see that the flash9.0 r124 plug-in is installed: after installing flash through the above method, some friends will feel that the browser's CPU usage will be relatively high, for example, open: http://news.sina.com.cn such flash more than the website, will find the system quickly slow, you can enter the command in the terminal: Top to observe the http://news.sina.com.cn, flash CPU usage, for example, my usage is as follows: the average CPU usage has reached more than 40%. Is there a way to optimize it? Method is still some, follow me to ^ _ ^: First we download the latest version of Firefox to the Firefox official website, address in the following: ftp://ftp.mozilla.org/pub/firefox/releases/3.0b5/linux-i686/zh-CN/ download firefox-3.0b5.tar.bz2 compressed package, put it in the/home/user name directory of the user, decompress the package, a Firefox folder will appear, and download a lower version of Flash 9 player (R31) at the address below: http://pickup.mofile.com/5266941889499040, and the file extracting, decompress the package to/tmp and copy all the files ~ /. Mozilla/Plugins directory. At last, right-click the desktop and select "create starter". The dialog box is displayed: Enter Firefox in "name", and enter "/home/your username/Firefox" in the command ", select a favorite icon and click "close". Now click the new link icon (Note: Do not open the default Firefox browser ), we will see that we started the downloaded Firefox, and then go to "tools-additional components" to see that flash 9 R31 appears in the plug-in: now let's try again to open the http://news.sina.com.cn, OK, Flash is also correctly displayed, and then enter the command in the terminal to see the current flash CPU usage, my situation flash CPU average usage has been reduced to about 13%, obviously, the optimization effect is obvious! (TIPS: Through the flash optimization method I introduced above, our system now has two Firefox browsers, one of which is the default Firefox of the system and the other is the Firefox in the user directory, it should be noted that do not overwrite the downloaded Firefox to the system's default Firefox. The overwriting may cause the system's default Firefox to fail to start. Another optimization method is to download a browser called swiftfox, which is an optimized version of Firefox based on different types of cpus. You can download it at the following address: http://www.getswiftfox.com/the current version is 3.0 pre1, it is much slower than Firefox updates) And if Flash garbled phenomenon, you can use the following two commands to solve: sudo CP/etc/fonts/CONF. d/49-sansserif.conf/etc/fonts/CONF. d/49-sansserif.conf.bak sudo RM/etc/fonts/CONF. d/49-sansserif.conf for friends who use FF in Linux, be sure to pay attention to whether the font is appropriate. Improper font will seriously reduce the FF rendering capability, try not to use compressed font and consider the use of TTF font, it is recommended that Wenquan translation is black font http://wenq.org /? Another powerful feature of zenhei Firefox is its support for extension plug-ins. These plug-ins can meet your various requirements for network applications. Many articles have introduced various powerful and fun plug-ins of Firefox, you can search by yourself and I will not describe it here. 5. Virtualbox optimization suggests that you do not need to tune the virtualbox memory option too high. Generally, the application redirects the memory to MB ~ MB is enough, and the memory is smaller. The speed of the virtual system will be faster. Remember to install the virtualbox toolbox after the virtual system is installed, only when the virtualbox toolbox is installed can the virtual system run faster and the hard disk data of the host can be accessed. 6. Experience in improving work efficiency using 3D desktops in addition to dazzling 3D desktops can also effectively improve work efficiency. The following is a summary of some of my experiences: Using window combinations to improve work efficiency ~ Three windows in the same group (for example, resource management windows and terminal windows) are combined, in this way, the super + left and right keys can be used to quickly switch between windows in the same group without the mouse. You can also use the mouse instead of the keyboard for quick switching. The advantages of window combination can also save the position of the lower panel, you can open more tasks on a desktop without switching the desktop. The advantage of using the ring switch on the desktop is that you can quickly browse all documents and quickly go to the relevant documents, if there are many documents, you can use the window tile effect without shift switch. The reason is: 1. There is no quick browsing effect. Because each document is overwritten, some documents will be blocked, and it is easy to switch to wrong documents, greatly reducing work efficiency. The only advantage is that it is relatively atmospheric, nice looking. I chose efficiency between efficiency and aesthetics. The avant window navigator awn can not only make the Panel look more dazzling, but also hide it automatically. The advantage of using awn is that it can save the position of the lower panel, increase the visible working area at the bottom. Open the hidden button of the upper panel. open the show hidden button in the attribute options of the upper panel. You can use this button to manually hide the upper panel, the advantage of hiding is, of course, to increase the visible working area above. In addition, if you do not want to see the frequently blinking Eva chart, manually hiding the panel is a good choice and use the shortcut keys to make the current window transparent, for example, if you want to take notes when reading an e-book, you can use the shortcut key to make the window transparent and partially zoom in. You do not need to move the mouse over the window, it will make you feel like flying. The following are your shortcut key settings: Transparency shortcut: compiz-Manager-> General settings-action-Opacity settings: Increases opacity: Alt + keypad 1 reduces opacity: alt + numeric keyboard 0 zoom shortcut: compiz-Manager-> enhanced zoom plug-in-> action-zoom movement: press zoom in super + keypad 1 area lock super + L level 1 super + End Level 2 super + keypad 2 Level 3 super + keypad 3 aere to windowsuper + z zoom left super + direction key left right super + direction key right up super + direction key down super + direction key zoom out super + number keyboard 0 use the rotating cube to improve efficiency through CTRL + ALT + The left and right direction keys, as well as the rotation through the edge of the mouse (my pointer edge rotation settings: "show desktop" in the upper left corner, "tile all windows" in the upper right corner, and "rotate cube to the left" in the lower left corner ", in the lower-right corner, you can quickly switch between different desktops through this setting. For example, you opened the Virtual Machine with vbox + XP on desktop 2, with the mouse over the edge, you can quickly switch between Linux and XP, which can only be described as refreshing. Use screen capture to enable screenshot. You can use the super + left mouse button to intercept the screen into an image at any time. Use the screen reversed color function. It is said that when this function is used to read text, the eyes will not be so tired.
