Me and ⁦@JesperBrouer⁩ wrote a blog post on the kernel’s BPF LPM trie implementation and cover some of the performance gotchas with the current code.

Awesome blogpost/talk + tool by @bristot : Linux scheduling latency debug and analysis https://t.co/CxOYUbOWQv Let's us look into the "blackbox" of Linux sched latency!😃

Fascinating discussion about raw sockets aka ETH_P_ALL https://t.co/KFZFJNNlAf The theory is that any socket AF_PACKET ETH_P_ALL socket also catches TX packets, working against TX zerocopy.

New year, new spikes - XDP with Mellanox 100G NICs does pretty good since we took it in prod🙂

Netflix/Intel working together to find low-level PMC-based perf wins in the cloud (by my colleagues Vadim and Harshad)

@JesperBrouer Thanks for telling us about all the cool stuff eBPF can be used for 👍🏻 #DrivingIT22

@RedHat funny feature to why you should use eBPF to unlock the potential of your Linux kernel 😉🙌🏼 #DrivingIT22

@toke_dk is telling us about decreasing latency #DrivingIT22

Next up at #P99CONF: @TalawahTech uses an HTTP benchmark to compare the performance of the #Linux kernel networking stack with userspace networking doing kernel bypass via DPDK. Grab your seat here: https://t.co/xog1f4gEzy #ScyllaDB

I'm very happy to introduce FastNetMon Community 1.2.3. This release includes a completely new network packet parser and XDP support. You may find the full list of changes here: https://t.co/ACD3AFj93i Installation:

Switching to Cilium Layer 4 Load Balancer XDP allowed @seznam_cz to drastically reduce their CPU consumption and increase performance Learn how in the video from @eBPFsummit https://t.co/xVZRTVvZJz

To achieve optimal speed and size of eBPF programs, use the latest version of the eBPF instruction set. By default llvm sticks to v1 which is non-optimal for most cases. pass -mcpu=probe to llc to auto-select latest instruction set supported by your kernel https://t.co/4KVyrwC2TF

This Friday @lizrice and @dave_tucker will be exploring bpfd which is a framework for running BPF tracers with rules on Linux as a daemon that is container aware eBPF & Cilium Office Hours Friday, 14th October - 9am ET / 3pm CEST Livestream: https://t.co/2UWO6xKkuG

One of the most fun videos about #bufferbloat #openwrt and #sqm I've *ever seen*. I am a huge fan of the right to repair also. Yay! @toke_dk @dsearls @doctorow @JimGettys @jlivingood

After a long wait, the first XDP based DDoS-Filter has landed in Frankfurt - throughout the week, all in! :)

Wondering how eBPF is changing edge computing? Come listen to @toke_dk from @RedHat explain how

Almost 2 days ago, we went live with our steaming new XDP Anti-DDoS approach at our partner @globedatacenter - nice to see it in action eating 85mpps, after months of hard development work 😃

Xdp hints...

Saw the slide live ;)
