Google Chrome Performance Issues

Over the past few months, I’ve noticed that Google Chrome’s performance has been rapidly going down hill with crashes, freezing and generally being slow. It’s also been failing to update itself completely properly. Today I decided to just uninstall it then re-install it. After uninstalling it, I went to go and delete all of the old Application Data, where, much to my suprise, the Chrome directory was 17.8GB with 126k files. Digging a little deeper, the vast majority of this data was in the “JumpListIcons” and “JumpListIconsOld” directories which are found in C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default. Screenshot below of the 17.8GB folder, I have to say it’s pretty impressive! You can click on it to see it full size 🙂

I have now run with my newly installed Chrome for about 5 hours, and it looks like the JumpListIcons directory is under control. Fingers crossed that is problem solved!

As usual, if you have any questions, comments or anything else, the commnets box is below 🙂

    That is a bit greedy of Chrome to say the least!

    For all its slickness, Chrome certainly isn’t perfect and Google aren’t completely infallible. One thing I’ve noticed that really gets on my nerves is when you’re getting directions on Google Maps and you add a deviations and pull the route about a bit the memory usage of the browser grows tremendously – so basically it seems a lot of the route planning is done client side. It seems Google don’t have so much regard for the resources on their user’s machines!

    Yeah, I had noticed that too. I guess its solving the TSP on your computer, so it’s not going to be light on resources. To be fair though, it would be hellishly expensive for them to do all map deviations server side.

    I noticed Chrome slowing too, plus I noticed when I was playing my favorite game that the window would mysteriously minimize. So a while ago I downloaded Sophos Anti-Rootkit and the first things it found were a bunch of “unknown hidden” files in JumpListIcons and JumpListIconsOld with names like 6059.tmp, 3630.tmp, etc.. Let’s see what happens when the scan is done and I try to clean them.
