My OperaAumente a Performance do Opera
Tuesday, November 4, 2008 1:01:30 PM
Opera is already a very fast browser, but if you would have the choice between fast and faster than fast, what would you choose ? I took the liberty to compile a list of 10 great tips that speed up Opera in several unique ways. Many of the settings can be changed by simply going to Tools > Preferences in Opera but some can only be used by accessing not so obvious ways like ini files.
Please note that everything that I’m describing here worked fine on my computer. It speed up Opera and increased my browsing experience with it tremendously. While most tips will work for any users no matter their connection to the Internet some tips might only increase performance for broadband users.
Disable Name Completion and local network lookup
Desabilite Completação de Nomes e Redes Locais
Whenever you enter a single word into the address field Opera will look in your bookmarks for that name and try to find a local network with the name as well. Server Name Completion tries to append prefixes and suffixes to the name automatically. While this feature might be great for some users it uses time and cpu and should be turned of for faster browsing.
Click on Tools > Preferences, select the Advanced Tab and choose Network from the left menu. Click on Server Name Completion and disable Look for local network machine and try name completion, using.
Clque em Ferramentas > Preferencias, selecione Avançado e escolha Rede. Clique em Completação de Nome de Servidor e desabilite Olhar por maquinas da rede local e completar novamente.
Increase the time cached images are used before checking for new versions
Opera downloads images to its cache to be able to load them faster (from your hard drive) the next time you visit the website. By default Opera checks every 5 hours if a new version of that image has appeared on the website. If you increase this time you increase your overall performance.
Go to Tools > Preferences and click on the Advanced Tab. Choose History from the left menu and select Every 24 hours or even every week for image checks. You can always refresh the cache manually by typing F5 while visiting the website.
Va ate Ferramentas > Preferencais e clique na Aba Avançado. Escolha Historico e selecione a cada 24 horas ou semanalmente para checar pelas imagens. Voce pode sempre atualizar a memoria cache manualmente apertando a tecla F5 quando estiver visitando um site.
Remove unneeded and duplicate plugins
Type opera:plugins in the address bar, this should display a list of plugins that are currently installed. Take a closer look and see if you find plugins that you never need. For instance if you never use Realplayer streams in Opera you should deactivate it.
Digite opera:plugins na barra de endereços, ira aparecer uma lista com os plugins instalados atualmente. Olhe atentamente e veja se ha algum plugin que voce nunca ira usar. Se voce nunca usa o Realplayer no Opera, desative-o.
To deactivate them open the file plugin-ignore.ini located in your Opera main directory and add the filename of the plugin that you want to disable to it.
Para desativar a abertura do arquivo plugin-ignore.ini, localize no diretorio principal de seu Opera e adicione o arquivo deste plugin para desativa-lo.
Another problem are duplicate plugins that are caused by loading the plugins from Firefox as well. This happens of course only if Firefox is installed on the same system. You can disable this easily by typing opera:config in the address bar. Navigate to User Prefs > Plugin Path and delete the Firefox reference there.
Alguns problemas duplicam plugins é causado pelo carregamento de plugins do Firefox. Isto não atapalha se somente o Firerox estiver intalado. Voce pode desabilita-lo facilmente digitando opera:config na barra de endereços. Navegar ate User Prefs > Plugin Path e deletar a referencia encontrada do Firefox.
Rebuild your profile if you have upgraded Opera (a lot)
This is only for users who upgrade Opera a lot. I for instance was using Opera since version 6 and always upgraded from the old version to a new one. This could mess up the ini files, especially the opera6.ini file which is still used in all versions of Opera. This could lead to all sorts of problems (slow page loading, high cpu usage)caused by obsolete or incorrect entries in that ini file.
The easiest approach would be to backup the file opera6.ini in your profiles folder of your Opera installation and delete it afterwards. Please note that Opera has to be closed before you do this. Restart Opera afterwards and it should automatically create a new opera6.ini file without all those old entries.
You will loose the personal information if you entered them in Opera and also all tweaks that you might have applied are gone too. It is however not a big problem to enter them again using the Preferences for the personal information and about:config for the latter.
Disable Turbo mode
Desabilite o Modo Turbo
While this might sound a little bit strange at first to disable turbo mode and present it as a tip to speed up Opera it becomes clear soon. Turbo mode means that Opera pre-draws any image which means that you see part of it although it is not fully loaded. This uses CPU and memory and could increase overall performance especially on slower computers. It should not be noticeable on fast computers though.
Type about:config and enter Turbo into the search field. Disable Turbo Mode and click on save.
Digite about:config e entre em Turbo na barra de pesquisa. Desabilite o 'Turno Mode' e clique em salvar.
Increase the number of total connections
Aumente o numero de conexoes totais
If you happen to load many tabs at once and like to read websites more or less simultaneously you might want to increase the maximum number of connections. This should have a drastic impact on loading times if you use a broadband connection. It should not make a big difference for users with slow connections, such as 256K connections or less.
Type about:config and enter connections into the search field. Change the value of Max Connections Total from 20 to another value, I suggest 32 or 64 connections. The Max Connections per Server setting should remain as it is. You might even want to test a lower setting, for instance 4 connections there.
Digite about:config e coloque 'connections' no campo de pesquisa. Mude o valor de 'Max Connections Total' de 20 para outro valor, Eu sugiro 32 ou 64 conexoes. A configuração 'Max Connections per Server' mostrara como ficou a performance. Se depois voce quiser testar um configuraçao baixa, coloque 4.
Reduce the amount of visited pages in history
Reduza o tamanho da lista de paginas visitadas do historico
Opera keeps track of the last 500 visited websites. The benefit is that Opera displays all urls that fit the string that you enter in the address bar. You can then scroll down and load the website without entering the url fully. This can however impact the time Opera needs to startup.
A temporary fix would be to clear the history manually, a better solution to reduce the amount of websites that Opera stores.
Click on Tools > Preferences and then on the advanced tab. Select History from the left menu and either click on Clear next to Addresses if you want to test if this solution really speeds up loading times or reduce the number of stored addresses in the history right away. I never use that feature and set it to 0. You might reduce it to 100 for instance.
Clique em Ferramentas > Preferencias e depois na aba Avancado. Selecione Historico e clique em Limpar proximo para 'Addresses' se voce quiser testar se esta solucao realmente melhorou o tempo de carregamento e diminuiu o tamanho da lista com as paginas do historico. Eu nunca usei esta caracteristica e coloquei 0. Voce podera reduzi-lo para 100.
Change Expiry Settings
Some Webmasters want you to load their website anew every time you visit it to display new ad banners for instance. This has the effect that Opera will not use the files stored in cache to load the website but request the complete website again from the server increasing load times.
We are however able to ignore the Expires meta tag from websites by changing two settings in the Opera configuration.
Write opera:config in the address bar, hit enter. Search for expiry and change the settings for Check Expiry History and Check Expiry Load to 1.
Escreva opera:config na barra de endereços, de enter. Pesquise por 'expiry' e mude as configuracoes do 'Checar Historico Expirado' e 'Checar Carregamento Expirado' para 1.
Save Images Faster
Salve as Imagens Rapidamente
This is probably more a usablity tip than a performance tip but I think it is still nice enough to be included. Instead of saving images by right-clicking on them and selecting Save Image you can simply press CTRL and left-click the image. The download window appears and you can save it then immediately.
Delay mail and rss connections at startup
Opera prioritizes mail and rss accounts during startup. This could mean that you could witness lots of disk activity during startup which could slow down Opera significantly. It is possible to delay each account individually to prevent that Opera slows down during startup.
Locate your accounts.ini file which should be in the Opera mail folder. Every account should have an entry Initial Poll Delay=X where X should be set to at least 60 (seconds) and the rss feed to something like 120 or more.
Localize seu arquivo accounts.ini que esta localizado na pasta do Opera mail. Cada conta tem sua entrada de 'Demora Inicial=X' quando X ficar como 60 (segundos) e o leitor RSS como 120 ou mais.
