Fixing Google Chrome Intermittent Lags & Freezes


Many people are experiencing temporary lags and freezes while browsing with Google Chrome. Consider the following suggestions:

1. As I suggested in a previous post try disabling the builtin Flash Player and Shockwave of Chrome. Then install Adobe Flash Player while all browsers are closed.

2.  AUTO DISCOVERING PROXY: The "auto detect proxy" function of Win 7 may be causing lag for some users. To disable it, go to Wrench icon in Chrome -> Options -> Under the Hood -> Change Proxy Settings. Click "LAN settings" and uncheck "automatically detect settings". Alternatively click Wrench -> Settings (if it's not grayed out) -> Show advanced settings... -> (Network) Change proxy settings button -> (Connections tab) LAN settings button -> uncheck "Automatically detect settings.". Hit OK until you get back to the browser. Test to see if the problem has gone away. You may also have to re-start Chrome.

3.  TABLET DRIVER/LOW LEVEL MOUSE HOOKS: This problem appears to be connected to "low level mouse hooks" causing problems in Win 7. Click the Start button, type 'services' and pick the Services item from the list. Scroll down to the Tablet PC Input Service and double click it. Click Stop, then change the 'Startup type' setting to "Disabled". Hit OK. If you run any other applications which change how your mouse functions (e.g. AutoHotKey), also kill those programs. Test to see if the problem has gone away. 


4.  Alternatively, instead of futzing with the Services, you can simply turn off Tablet PC Components as a Windows feature:

A.  If viewing the Control Panel by category: 
Control Panel > Programs > Turn Windows features on or off (under Programs and Features) 

B.  If viewing the Control Panel by icons: 
Control Panel > Programs and Features > Turn Windows features on or off (left side panel) 

In the list of Windows features that pops up, simply uncheck "Tablet PC Components" and hit OK. 

5.  Clear the Chrome browsing history, cache, etc. You may use CCleaner and Glary Utilities for thorough cleanup.

6.  I think Chrome, during those temporary lags and freezes, is trying to use memory that Microsoft is busy loading with random crap. Super Fetch is a random crap loader. It isn't a virus or malware; it's one of those problematic features that attempts to load things you MIGHT need before you actually need them based on what you needed yesterday. A feature that front loads more and more overtime? Super Fetch service is a memory drain too that seems to slow down Chrome browsing. Look in the Task Manager for svcHost that has 100MB+ memory usage. Right-click it, go to Services. Turn off and then disable Super Fetch.

7. I also noticed after installing the Adblock extension that it's causing some lags to Chrome. Seems like disabling the AdBlock extension makes things smoother (not perfect, but better) for me.

8.  A.  Click Start, point to All Programs, and then click Accessories. 
B.  Right-click Command Prompt, and then click Run as administrator. 
C.  In the Administrator: Command Prompt window, type the following command, and then press ENTER: 
netsh interface tcp set global autotuninglevel=highlyrestricted 
D.  Reboot computer. 
The problem is described in Microsoft KB Article 929868: http://support.microsoft.com/kb/929868

9.  One more thing you should try. Defrag your hard drive. I know it sounds simple, but Nike said, "Just do it!" (hehe... hopefully). In Cmd prompt, enter this command:
defrag c: /U /V 

10.  Back up your files that you can't afford to lose in your Documents and Settings account folders. Then re-install Chrome using RevoUninstaller. Give the hidden folders a clean out before re-install. Make sure Google Chrome is closed and none of its components are running in your Task Manager. If there are some stragglers there, END TASK them at once.
For Windows Vista - C:\Users\<username>\AppData\Local\Google\Chrome
For Windows XP - C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome
Sorry, I don't have Windows 7 here.

11.  This site suggests deleting the Local State File and renaming the Default folder in the Google Application Data folder:
