In case you do not know about them, Chrome Flags are essentially plugins or setting tweaks which are majorly in the experimental stage.

They are in the experimental stage, a reason sufficient enough for the developers to set the Chrome Flags off by default for the end user. This, however, does not mean that you can not fiddle around with them.

There is an astonishing number of Chrome flags available in a hidden area in the Chrome browser which you can access by typing the following and hitting the enter button:

chrome://flags

Coming back to the point of discussion over here, if you do not know the bugs or errors which are making your Google Chrome slow, you have to try these Chrome flags for sure.

Even if you know what things are making your Google Chrome slow and you have tried to fix them somewhat, good for you, you can still make use of these tips and improve your browser performance to a whole new level.

So, without wasting more time, let’s learn about the list of the best Chrome flags to speed up your Google Chrome:

1. “Stale-While-Revalidate” Cache Directive

The “Stale-While-Revalidate” Cache Directive is a directive which enables the cache to serve a response even if its max-age has expired. This permits servers to specify that some resources may be revalidated in the background to improve latency

Enabling this feature would result in a better cache reuse, lesser blocking resources, a faster browsing experience for you, restricting the processes which make your Google Chrome slow.

2. QUIC Protocol: fixes the main things which make the Chrome slow

QUIC Protocol is one great data speed hack for your Google Chrome. The QUIC or the Quick UDP Internet Connections is an in-house experimental Chrome flag from Google. It was developed way back in 2012 and it is a surprise to see that it is still an experimental feature as it was submitted to the IETF for standardization back in 2015.

The main focus of the QUIC Protocol is to reduce bandwidth, latency period, and the unnecessary network congestions which it achieves by decreasing the number of round trips needed while establishing a new connection, one of the reasons which make your Chrome slow.

All the major platforms including Mac, Windows, Linux, Chrome OS, Android can make use of this Chrome flag and this is one good hack to speed up your Chrome by a good margin.

3. TCP Fast Open

The TCP Fast Open Chrome flag allows the browser to send extra authentication information in the initial SYN packet for a previously connected client, allowing faster data send start.

It basically helps in speeding up the opening of data channels across points.

By enabling this Chrome flag, you are basically allowing the data to start being sent/received more swiftly thereby making your Chrome browser way faster than usual.

This Chrome flag, however, is not widespread across all the platforms. If you are a Linux, Chrome OS, or an Android user, you can make use of it to prevent your Chrome from getting slow.

4.Speed up your Google Chrome by Increasing the number of “Raster Threads”

“Raster threads” are an important feature gone unnoticed most of the times. To make it short, Raster graphics are those graphics which make use of pixels to form an image.

All the websites present on the internet make use of Raster graphics or rather Raster Images. Raster threads are a means for the computer to interpret and read those images.

If you ever face a situation when the images on any web page you open take a lot of time to open up properly, you should definitely be making use of this hack. The reason for the images not loading up quickly might be any, but the end result will be the same – it will render your Google Chrome slow. This Chrome flag will fix this situation up for you.

All you have to do is to maximize the number of Raster Threads from the drop down menu. Choosing 4 as the value will make the image loading the fastest and surely it would speed up your Google Chrome as well.

5. Only Auto-Reload Visible Tabs

If you enable this Chrome flag, pages that fail to load while the browser is offline will only be auto-reloaded if their tab is visible. This is not a direct way to speed up the Chrome, but it certainly would allow you to control the number of tabs you actually want to auto-reload. If you happen to have a lot of tabs opened up and if all of them reload at the same instant, this would surely make your Chrome slow.

The Auto-Reload Visible Tabs Chrome flag is by default not enabled. All you have to do is to enable it from the drop down menu.

This was the list of the best Chrome flags which will speed up Google Chrome for you. Using these, you would definitely feel the change in the way your browser works.
