Thanks for posting this. I just made a donation to the PSF.

Cloud specific features and optimizations, particularly geared toward AWS hardware. Also a combination of a 2 year release cadence and 5 years of Amazon backed of support for each …

Ships with kernel 6.1. Nice! Also has the most recent releases of bpftrace and bcc. Full package list: https://docs.aws.amazon.com/linux/al2023/release-notes/all-p...

> It's not actually an HTTP server though... Correct, it is a fake HTTP server, serving a real HTTP workload. This post is about comparing two different networking stacks (kernel v…

Yea, it is definitely a fake HTTP server which I acknowledge in the article [1]. However based on the size of the requests, and my observation of the number of packets per second i…

Very cool! Most of my bpftrace usage has been on the kernel side, but out of habit I often fall back to the debugger (or printf) in userland, which can seriously distort analysis o…

Sure, I was just pointing out that their current rates are cheaper than gandi, especially for renewals. So if someone wants to renew for multiple years it may make sense to switch.…

No, I confirmed that it is for all years. They deliberately don't make money on domain name registration. The use it to attract/retain business for their other services.

FYI Cloudflare currently charges $30 per year for .io domains.

AWS re:Invent is this week. This was announced as part of the CEO's keynote. I am sure we will get more details throughout the week in some of the more technical sessions.

I was wondering how they were going to manage the fact that AMDs Zen3 based instances would likely be faster than Graviton2. Color me impressed. AWS' pace of innovation is blisteri…

I wear bluetooth headphones which are connected to my Android TV player (Nvidia Shield).

I don't go flat-out, but it is definitely high-intensity. I am always out of breath at the end, but not collapsed on the floor. When I started I was doing around 2:05/500m. Now I a…

I've been rowing twice a day, every day since the pandemic and it has been a game changer. A high intensity 2k (while listening to music) in the mornings before I start my day, and…

1.2M req/s means 2.4M (send/recv) syscalls per second. I definitely think io_uring will make a difference. Just not sure if it will be 5% or 25%.

The answer to that question is not quite as straight-forward as you might think. In many ways, this experiment/post is about figuring out the answer to the question of "what is the…

Hard to say exactly. I have been working on this in my spare time, but pretty consistently since covid-19 started. A lot of this was new to me, so it wasn't all as straight-forward…

The MTU is 9001 within the VPC, but the packets are less than 250 bytes so the MTU doesn't really come into play. This test is more about packets/s than bytes/s.

I didn't make any coordinated omission changes (I really didn't make many changes in general), so twrk does what wrk does. It attempts to correct it after the fact by looking for r…

That is an area I am curious about as well, especially if you throw io_uring into the mix. I think most kernel bypass solutions get some of their gains by just forcing you to use t…
