Google Chrome cache performance

This is a very interesting read about Google Chromium cache performance.

For example: "How long do you think it takes for an average Windows Chrome user to fill up the browser cache? Well, for those users who filled up their cache , 25% of them fill it up in 4 hours. 50% of them fill it up within 20 hours. 75% of them fill it up within 48 hours. Now, that's just wall clock time...but how many hours of "active" browsing does it take to fill the cache? 25% in 1 hour, 50% in 4 hours, and 75% in 10 hours. Wow. That seems really quick to me. Remember though, every resource goes into the cache, in order to support back-forward navigation."

Now this part is frightening: "So, a quickly filled up cache is a one reason why servers perceive a lower than expected cache hit rate. While chatting with Ricardo, he drew my attention to a few other anomalies in our metrics. First, a surprisingly high number of users like to clear their cache. Around 7% of users will clear their cache (via chrome://settings) at least once per week. Furthermore, 19% of users will experience fatal cache corruption at least once per week, thus requiring nuking the whole cache. Wow, the cache gets wiped, either explicitly by the user, or due to corruption, for a large chunk of our user base. We definitely need to investigate what's up with all this cache corruption."

I just looked back at the annual State of Browsers on Geekzone March 2013 and comparing to current stats I found that Google Chrome just went up to 44%, Firefox went down to 22% and Internet Explorer went down to 18%, in only seven months. That’s a huge shift towards Google Chrome.

How do you folks think this impact in someone using Chrome in terms of perceived performance? Have you ever noticed any performance change over the course of weeks when using Chrome? And with Internet Explorer 11 for Windows 7 available now (which includes performance improvements, compatibility, SPDY support and more) how is this going to affect things?
