Is the TTFB for different locations and browsers irrelevant if you are self-hosting?

[danatanseo]

Thanks Vadim. Yes, this Cloudflare post is exactly the one I was referencing in my question. As I mentioned, Ilya Gregorik posted a rebuttal to their experiment here: post in Google+

It seems to me that if a Google developer says TTFB absolutely does matter that this would take precedence over anything Cloudflare might say.

What do you think?

Yea this makes sense as others have said that Cloudflare is trying to say that TTFB is not the most important metric, and so they published this study, as it aids their business model.

I would do just that listen to Google dev vs Cloudflare. Also the way I think about it even if their studies are true, where for the overall benefit TTFB would have to increase if you are using some compression, you still need to work and decrease your TTFB either way, that is just intuition. I apologize if I made it seem that TTFB is to be ignored, because Cloudflare state's that quite boldly,

Again some things that affect TTFB:

1. Move your website to a faster/better server (If an option)
2. Use a CDN or something similar to reduce the load on the server (repeated requests to a server will increase the TTFB)
3. Reduce the time the server spends processing the request for information (sent above) and more here: http://stackoverflow.com/questions/10938682/how-to-reduce-server-wait-time

I absolutely agree with Vadim. (+1)

Google is the best source for Google facts. Everything else is just speculation.

And yes, generally speaking, the best answer is to use a CDN.... 
The reason is simple. CNDs proxy technology, which was designed to minimize "physical" distances between the site's content and browsers, directly influences TTFB.

Being an in-house SEO for a CDN company I get a lot of questions about this from our support and clients. I have to admit, until recent Moz post, I wasn't aware of full implications of TTFB and considered it to be one of few page load speed related metrics.  (http://moz.com/blog/how-website-speed-actually-impacts-search-ranking)

This post really helped me get a better grasp on things. Interestingly enough, few month ago one of our clients Guest Posted in our blog about speed improvement gained by our free plan. Among other things, he mentioned 70% improvement in TTFB (grade going from F to A) 
(http://www.incapsula.com/the-incapsula-blog/item/718-what-incapsula-free-did-for-my-site)

At the time I didn't give it much attention. Because, like many others, I was focusing on overall load speeds.... 
Now I can't help but feel that this was a missed opportunity.
This post could be even better with the added SEO angle...
If anyone here is interested in giving this a try and guest posting about it, I`ll be happy to provide all resources needed on our end.

Hi Igal,

Do you work for incapsula, you are mentioned as a Mod on the blog?

I have heard great things about incapsula from others, but in terms of TTFB is it better than cloudflare? If so, how so?

Also any other ways that it excels Cloudflare? any ways its inferior to Cloudflare in your opinion?

Thanks I am really looking for more info, as I had great results with Cloudflares features and offering, wondering if I should give Incapsula a run

Thanks

Hi Vadim

Thanks.
Yep, I work for Incapsula but no, we are not the said "Mod".  

As for CF comparison... Generally speaking, we are more business oriented and security focused. I know that our security offering is more comprehensive, especially because both WAFs were comparatively pen-tested on several occasions and we always came out as consistently (and significantly) better option.We also have addition security features - like 2FA support and backdoor shell protection - which CF simply doesn't offer and we do more in way of ddos mitigation, especially against smart application layer attacks which require security capabilities, besides network muscle.

Still, speed wise, I always considered us to be pretty much on the same level. However, until few days ago I never considered TTFB to be such core SEO factor, so maybe we have better performance there...  
But again, to be fair, I`m only speculating - mostly based on the CF blog you've shared.
(if TTFB is considered un-important, it might also be under developed...)

Might be an interesting thing to test and document.

[vmialik]

security wise it seems both of you guys have stellar options. for me the issue is performance, caching for dynamic sites, CDN performance, and in this case TTFB response.  I was not sure with your response do you have faster TTFB to CF?

Thanks

[Igal_Zeifman]

Honestly, I don't know. I don't think TTFB was ever comparatively tested - at least no to the best of my knowledge.

For security, these are some of the resources I can point to.
I understand that this is not the main issue
Still, I wanted to provide some factual context to my previous statements.
