If you have noticed that the Google Chrome browser or Google Now are very slow on your Android device, while other browsers that you have installed on it are not, then you may be able to fix this with a quick change of the preferences.
Open Google Chrome on your Android device. It does not really matter which version of Chrome you are using, as all can be fixed by this.
Once you have opened the web browser, tap on the menu button of the device and select Settings from it. This opens the preferences that are separated into various menus.
Locate the Developer Tools menu here and tap on it. You find three items here. If either of the first is enabled, uncheck them to disable the feature.
- Enable Tilt Scrolling - Allow scrolling of the stack view by flinging the device. Changes won't take effect until Chrome is restarted.
- Enable USB Web debugging - Debug web pages from Chrome Desktop via USB.
This works only if you do not need one of the settings. Since it is possible to re-enable the features again at a later point in time, I'd suggest you disable them even if you need them just to see if it resolves the issue and speeds up Chrome in the process. (via Josh)
The second tip may help you if you experience lag or slow downs when you are using Google Now on your phone or tablet. This works only if you do not need the phone search feature of Google Now.
Open the app on your device, tap on the menu button and select settings from the menu. Locate the phone search menu here and tap on it.
Disable any search option that you do not need including apps which just searches for the names of apps that are installed on the phone or tablet.
Once you have done so test the change by using Google Now as usual. (via Caschy)
The preferences in Chrome and Google Now that are responsible for the speed drop are not what I would call essential for the majority of users. Especially the developer options in Chrome should be turned off by default in my opinion, and only turned on by the user.
If you are making the changes, let me know if you notice a speed boost or if the fix did not help resolve it at all.
