Yes, really, and no, only you and phk have shown this paranoia; most the userbase here agrees by votes. The software I'm discussing is all free open source software and anyone can test for themselves in their own environment to call b

Nothing to do with sendfile, you claim that TLB management is "a hardware problem" which is completely wrong, whatever you think you know about virtual memory has no foundation and anyone with a basic understanding of computer arc

These are both fair points, my perspective is from high scalability and some of the public technical marketing about its scalability wound me up.

s/shaping/pacing/, we're trying to smooth out the bursty nature of sending from high speed links and TSO so a flow is less likely to incur large contiguous buffer drops and tail drops along its path rather than limit the

You realize that's a fraction of what other like software can do on Linux right? I can't share our in house comparison, and they're on a modified FreeBSD vm and network stack so it's not applicable to the public anyway.

We have a legacy platform that has been rototilled over the past few years to work above 100g. That path was just reality to provide continuity of features and lessen the risk of overhaul over several years vs a brown/greenfield. Not

I apologize for being curt here but you haven't demonstrated enough background in computer architecture for me to continue the discussion in a worthwhile way. If you don't understand how nginx workers and varnish workers differ,

I definitely have hoarding tendencies. I have 100s of vintage UNIX computers, 1000s of books on CS and EE topics. I mostly find the idea of them inspirational, even if I rarely get to explore them in the depth I wish to. But the hoarding

Correct see i.e. https://book.varnish-software.com/4.0/chapters/Tuning.html#t... - a worker thread is used per request rather than industry standard polling loops for this kind of application. That doesn't m

You don't understand TLB. It is distinctly not a hardware problem. A TLB is a content addressable memory and the mappings and flushing are done by.. software. You flush it every time you context switch, and pretty much fully all the

You keep accusing me of logical fallacy but are using them yourself so I can't have a rational conversation with you. There is little CPU idle when you are doing TCP packet pacing, TLS in core, and edge compute. That's what I do

Yes as I said Varnish has great fit and finish. If you have a small pool of servers my comments will mean little to overarching business decisions. To clarify my own part, this was in the back of my mind http://varnish-cache.org

It's not about you in reality, just trying to save users some headaches. On the contrary you have no idea what I have tried and more importantly what rigorous comparisons my company has done to select the basis for our products. Ther

Two of the earliest and biggest CDNs are based on squid. Very hacked up though. I have no direct experience with squid3.

I work in the CDN industry and am also heavily involved in the FreeBSD community. I find Varnish to be kind of a tragic curiosity in that is has nice fit and finish but is pretty unsuitable for high scale workloads due to the influence of

They are also showing signs of fatigue in the data center space which carries high margins. The underhanded I/O game they are playing is both alienating customers and providing a big opportunity for AMD, IBM, and Arm.

As soon as there's a committee it's almost certainly going to be philanthropy rather than art. The presumption is that you have excellent taste and exercise Steve Jobs-esque tyrannical control over the aesthetics.

Don't get me wrong it would totally be about ego and about how excellent your own design tastes are. You'd name all the stuff after yourself. That's why it'd be considered art :D Some of the robber barons did some inte

One thing I've never understood - and if I ever become absurdly wealthy I will try these kinds of random absurdities - is how few of the rich use the power they have to create new definitions of art. For instance, sure you can commiss

Maybe misparented comment? HP has GenZ, IBM is going to move from DDR or DDR buffers to CAPI attached RAM -- expect to see HBM2 attached to CPUs in 2019. I'd be happy to discuss that kind of thing in email.
