First Byte Time “FBT” findings and research results

RE: First Byte Time “FBT” findings and research results
It seems like Anton is suggesting that reducing bloat could improve TTFB but doesn't actually know why, even though he's seen it happen in the past.

No one else thinks it's possible because the server can't possibly know what assets are even going to be called until the HTML requests them which is after FirstByte.

IMO he's right though, If the same resource is serving pages and assets.

The bloat from YOUR requests wouldn't affect your TTFB but the bloat from the rest of the traffic on the site could be reducing capacity and affecting your TTFB.

Well, this is a Magento demo site. What CMSes have you optimised, and where are the examples? You're coming over as talking a good fight at the moment.
Fighting what? This idea that every site needs a CDN? I'm not even sure what you're trying to argue.

I could link you to literally dozens of sites I have optimized but what really is the point? While I'm here legitimately helping people, you're just being argumentative, muddying the waters and giving mostly advice the basic site owner can't even follow. It's like you are more interested in showing off your tech acumen rather than providing actual help.

Newsflash - nobody cares about your advanced knowledge, they just want help understanding WPT, and how to use the tools it provides, and mostly need just the most basic help and advice. The essential stuff they can actually do. That's what I volunteer my time, doing.

And what do I gain from 'showing off' Anton? It costs time and effort to respond, and I really don't need any more work that's for sure. I just get hacked off when people spout absolute crap which often requires Scotty changing the laws of physics.

This thread is about the TTFB of a site. For all practical purposes, payload like images, css and js have no effect on this, as they are loaded *after* the pages html, delivery of which is what we're talking about*. And yet you tell us differently, but provide no evidence.

SysAdmin isn't hard. It just requires information, logic and time to digest and analyse, and these are the skills required to tune a website ( whether they're done for you on a shared host, or you have control of them is a separate question ). Gut feelings are a good starting point but, like any hypothesis, it needs analysis, investigation and proof to be of any value. I'm not showing off, I'm attempting - by example - to get you to complete this process. Something you're refusing to do.

I certainly don't know everything - I left the Dunning-Kruger part of my career around a long time ago - and am still learning about getting the best out of linux servers 3 decades after starting in the field. For me responding to these queries is pay back time for an industry that's looked after me quite well over the years.

*unless you're obviously gaming the system.
