Are you able to measure the latency of processing one request when there is no load? Just back of the envelope, if it takes 200,000 instructions to handle a request and we assume 6 cycles per instruction, then that’s about 25 requests per s

I don’t send more emails than the average user. I send ~3 emails per week.

A link between zeroth powers and the logarithm function is such a simple idea but potentially fruitful. Exponentials and logarithms often translate between additive groups and multiplicative groups. Maybe there are interesting isomorphisms

Linux also depends on GCC or compilers that share its behavior w.r.t. type aliasing.

C compilers should really refuse to compile code that does blatant type punning like this. Is there a book out there that is teaching people this is okay? Everything I’ve ever learned about C/C++ has explicitly warned against type punn

I’m not a business. I don’t send mass emails. I never have.

I appreciate the critical thinking in this post. Something every parent should do. We should talk about these issues more openly rather than accept what is being pushed into us.

Completely unique email from a new domain that has never mass emailed anything gets put into the spam immediately. It’s a very small chance anyone has ever clicked spam on my email. If it’s a matter of the domain being “warmed up” then I ba

Yes, it says it has no data on my domain.

Yes, and other domains and other IPs.

I don’t think this is true. The only people I sent email to are my friends or people with whom I do business. This server is for personal use.

Because in the proxy setup you get to keep your TLS private key on your own physical infrastructure. The VPS is just passing opaque packets. If you value the privacy / integrity of other data then that also is more protected.

I don’t necessarily disagree with you, just wanted to draw a distinction between a blatant failure to manage finances and an excessively aggressive growth strategy that fails to pan out.

It might be hard to believe but that is closer to the norm than not. Unicorn-bound tech startups tend to operate by spending all their cash to grow the business as fast as possible, intending to raise another round once the previous round d

But in this setup, only a single process can use the logical device provided by the NIC. In kTLS case then multiple processes can share the logical device transparently.

Hmm I’m not sure you’re responding to what I’m saying. The C code is not an apples to apples comparison with the custom assembly when comparing the speed of an indirect call to a direct call. Do you deny that?

by CyberRabbi 5y ago
Unless he uses the same custom assembly except with an indirect call, it’s not a good comparison. We can’t be sure the increase in runtime is due to the indirect call.

by CyberRabbi 5y ago
It’s not an apples to apples comparison unfortunately. He’s using custom assembly for the direct call benchmark but C code for the indirect benchmark. The C code contains no optimization annotations either, the compiler could be inlining th

I’ve never left desktop computers and laptops are terrible for your posture.

Are direct calls really all that much faster than indirect calls on current x86 archs? I was under the impression that it’s more or less the same on the current generation of CPUs. Those CPUs do a decent job of branch predicting indirect ca

To be fair the hardware in question is not just accelerated crypto operations. From what I’ve read on this topic there are network cards that handle the end-to-end TLS protocol (sans negotiation). In general you have a point but it’s a judg

Generally the kernel is involved when it comes to making use of hardware. Specialized hardware emerges when widely applicable bottlenecks are identified, like rendering 3D graphics, decoding video, or in this case TLS encryption. Not everyt
