Browser Tweaks and Tricks: How to speed up Opera?

Increasing total connections

• Type about:config in the address bar
• Enter connections into the search field
• Change the value of Max Connections Total from 20 to any value between 32 to 65
• Do not change the Max Connections per Server
• After you are done with the above just save the settings and restart browser

Name completion and local network machine

• Go to Tools> Preferences> Advanced> Network(or click Control and F12 same time)
• Select Server name completion
• Now you have two options within it.
  "Look For local network machine"
  "Try name completion"
• If you uncheck both of the above options, i.e.; Try name completion and Look for local network machine, Opera will stop cycling your CPU, trying to guess what you’re typing in the address bar
• Restart the browser after applying the settings. You’ll see the speed difference

Reduce the amount of visited pages in history

• Go to Tools> Preferences> Advanced> History (or click Control and F12 same time)
• Reduce addresses to 100 instead of 500 by default

Opera loading

• Go to Tools> Preferences> Advanced> Browsing> (or click Control and F12 same time)
• In the loading window choose "Redraw Instantly"

Tooltips
