How to Change Chrome Cache Size for better Performance ?

Current Google Chrome Cache Size

Is your browsing speed slow in Google Chrome ?  One thing to improve  is to increase cache size. But there can be other reasons why Google Chrome is slow.  Other browsers like Internet Explorer and Firefox have a direct way of increasing their cache. But there is no good interface to know directly what is the current cache size in Chrome. For this you need to apply round-about techniques.Cache is a temporary memory location on your drive. So this occupies some space.

For example, you are frequently visiting a website, which has some static resources. So instead of Chrome fetching these resources every time from the server, it will try to locate the cache folder and present data of these static files.

You will start having problems if the cache exceeds a certain limit, as that will up the disk space. So it’s always better to restrict the cache size to a limit. But first let us know some basics of Chrome Cache.

What is Google Chrome Default Cache Size?

There is no set default limit in Google Chrome.  It can start at a minimum of “zero” and can reach “1GB” sometimes.

The default size is calculated at start time. It depends on the available disk space on the drive where the cache is located.

But how do you know what is the current cache capacity? There is no direct way to know it as well!

Type the following command in the Chrome address bar.

chrome://net-internals/#httpCache page

This will display the following information in the window below.

As you can see above, you can find lot of data on various parameters. But if you click “Cache” on the left hand side, different attributes are displayed on the right.

One of them are Current Size and Max Size. I think these are the current and maximum values of cache in bytes. This information will be useful to increase buffer size in Google Chrome.

Where is Chrome Cache Location?

You need to check the setting that says “Show Hidden Files and Folders” before you see the cache folder location. Then you go to your “Windows” drive which is generally C: and under the “Users” folder, locate your <User> folder. Then navigate to the following path.

“AppDataLocalGoogleChromeUser DataDefaultCache.”

This information will be useful little later in the article.

Using Regedit

Another way to improve cache size is by setting a DWORD to the required limit in the policy setting below, by editing the “Registry” in Windows.


But sometimes this policy setting is not adhered to. Even if you are using the latest version like 35.x, the cache size determines the maximum size for caches files. This is normally 1/8th of total amount in bytes.

The cache settings in Google Chrome are little different. Painstakingly you have to modify some options. The procedure to increase browser cache in Google Chrome is as follows:

  • Right-click the Google Chrome shortcut on the Start menu or desktop and select “Properties
  • Click the “Shortcut” tab at the top of the “Google Chrome Properties” window.
  • Click the “Target” field, and push the “End” key to move the cursor to the end of the text.
  • Push the space bar once.
  • Type “–disk-cache-size=10000000” in the field, modifying the number after “size=” so that it represents the space that you would like to devote to the Google Chrome disk cache in bytes.
  • Click “OK.” Close any running instances of Google Chrome, and re-open the browser to begin using the new cache size.

Using Group Policy Editor

You can use the following info from this post to apply the change in chrome cache size using Group Policy Editor. In short, you are going to download some policy templates. There are certain admx folders in this downloaded templates. You then copy the chrome.admx file to PolicyDefinitions folder. Then you are going to make some changes using gpedit.msc policy editor.


Sometimes the above solutions may not work. For example, if the cache folder takes more space than set limits, there can be left overs that were left behind. In that case, it is better to close the browser and manually delete all cache files. The cache folder location mentioned above, will be useful here in clearing the cache. There are other cache folders which Chrome uses, which can take extra space. These are –

  • Application Cache – HTML5 Application Cache
  • GPUCache – GPU shader cache
  • IndexedDB – HTML5 Indexed Database
  • Media Cache – Multimedia-optimized cache (audio and video clips)
  • Local Storage / Session Storage – Web storage cache
  • PnaclTranslationCache – Portable Native Client Translation Cache

Though we can limit some of them, it’s not possible with some of them.

    Just in case others wonder why it does not work…
    Use two lines before disk-cache-size

    The registry key needs Backslash characters to separate different keys and subkeys.
