cloudflare optimization

Does Cloudflare live up to the hype?

I have given Cloudflare a try for the past week or so for and want to pass along my thoughts.  I saw a few reviews that were quite astonishing and decided to find out if they are accurate.  I have been reading great things about it and couldn’t resist trying it out.

Will Cloudfront Increase Pages Per Visit?

Unfortunately no.  The only reason you’ll see an increase in pages per visit is if you change the setting to add your Google Analytics code to every page.  I decided to use this myself and look at the results:


Notice the bump in pages/visit?  Almost double.  That is when I added the Analytics code to every page and it completely skewed everything out of whack.   Meanwhile GetClicky and awstats both showed them to be at normal levels.  So clearly this Cloudflare setting should not be used and anyone who shows these type of drastic results are just lying to themselves.

I obviously don’t think Cloudflare adds this setting to artificially increase analytics stats.  Although, I can’t explain why this happens, since they claim its fine to add without removing the old code.

Will Cloudflare Decrease Bounce Rate?

Probably not.  If anything, it could have a slight increase in your bounce rate depending on how much bad bot/spam traffic you were getting.  Although, a bad bot might even help your bounce rate because they are often times so abusive and load many pages.  If Google Analytics shows a drastic decrease in bounce rate then it is due to the Cloudflare setting to add the script to every page.  Have a look at my bounce rate:

Sorry folks, Cloudflare is no miracle bounce rate solution. 🙁

Will Cloudflare Increase the Speed of the Site?

Yes, even using their free service!  Cloudflare has a whole list of features that show how they can decrease the time it takes for a page to load.  They will cache content, similar to a CDN and provide optimized routes to your site, and block abusive traffic.  If you pay for their service then you will see even better benefits (none of which I have tested).

So I guess the real question is, does Cloudflare make FantasySP faster?  Yes and no.  I have most of my static content already on Amazon’s Cloudfront.  My DNS before Cloudflare was Amazon’s Route 53.  So how much of a benefit am I really getting when some of Cloudflare’s services were already taken care of?  Here is a look at Googlebot’s time it takes to crawl

Googlebot Crawl Rate

According to Googlebot, the site isn’t faster, perhaps slightly slower if anything.  It could be that Amazon’s Route 53 provides equally as good routing for end users and I don’t see much of a difference.  Either way, there isn’t enough evidence to make a call on this.  What really matters is if there is a difference for the end user in a real browser.  For my site, javascript is what is holding back the end user experience.  Which brings up my next point, Rocket Loader.

Does Rocket Loader Improve Speeds?

To test Rocket Loader’s performance, I will be using NewRelic’s End User performance tracking.  I have been using this for well over a month and it should show any trends with end user speeds.

As you can see, there is a large decrease in pageload time and goes from 8 seconds to 6! Awesome right?  Well, unfortunately I noticed that Rocket Loader was screwing up some of the rendering of advertisements that were on the site.  Thus making my site’s javascript unusable.  Rocket Loader works fine with Google AdSense, but AdSense doesn’t generally hang as much because of their recent optimizations.

What I really wanted Rocket Loader to do, was to improve performance of the other ad networks that I use.  These are the ones causing all the slowndown.  Alas, it wasn’t meant to be.  Clearly it was making a difference, but it is a bit buggy at this point.  My next step is to selectively use Rocket Loader on certain javascript components and see if it will make a difference in overall load time without breaking things.  Stay Tuned for that!

So Where Does This Leave Us?

After reading all of this, you might think I’d come to the conclusion that Cloudflare isn’t worth the trouble.  Exactly the opposite.  Cloudflare delivers on a lot of the promises of the service.  Just be sure you don’t make mistakes like enabling Google Analytics on every page.  That feature just doesn’t make any sense to me.  (I’d love to hear your thoughts on this.)

If you aren’t using a CDN or a customized DNS service, then switching to Cloudflare should have an impact on quicker load times.  Even if you do have a CDN and a customized DNS service, the fact that Cloudflare blocks bad threats and saves your server resources and prevents lots of spam.  It’s also nice to see trending data for search engine bots and outbound links.

I’d love to try out Cloudflare’s pay only services to see if they improve upon speeds, but they do not offer a trial for such a thing.  Perhaps down the line I will test these as well.  I also think Rocket Loader will continue to improve and will truly make a difference for some users out there.

What do you guys think?

CloudFlare should decrease bounce rate as well as pages per visit because of faster load times. this would be evident if you weren’t using a CDN before hand.

We’re looking into your issue with Google Analytics on For most sites it works great. 
If an old version is detected it’s replaced by a more recent Analytics code, and if it’s already present we don’t make any modifications.


Took me some time to reach it on my TODO list, but I think I’ve identified and fixed the possible double count when using the CloudFlare Google Analytics insertion option.
This should be live soon, in our next push.
Thank you for pointing out the issue, and let me know if you still experience any other problem with our features.


Hi and thanks for sharing your point of view. 

I put CloudFlare to the test and it does work as far as improving performance, i.e. loading speed goes. But as you too found out, it may not increase pages per visit or decrease bounce rate, CloudFlare is no miracle potion, and here the old adage of content is “king” still holds true. And Rocket Loader is definitely still very much beta.While I enjoyed being on CloudFlare, it wasn’t 100% what I was looking for, and so I found a similar service that was more suited to my security needs while at the same time improving my performance: Incapsula.

Something to consider.

I like the service (free). it has blocked over 20 bad bots in 3 days, which is always good.

it rekons it has saved 50% of both page requests and bandwidth, which is a ++

but i have noticed the past day or two that my site has been down for up to 10 mins about 4-5 times. im gonna check with them now.

Check this test site out I use.

The first massive drop in bounce rate is due to speeding up my site, after adding Cloud Flare bounce rate is on the rise. Like you I agree that this is likely bot/spammer traffic.
