You mean like this one directly from AMD showing a median 1/2 RTT ef_vi latency of 590ns (for UDP)? Using their latency generation card that came out just a few months ago? https://docs.amd.com/r/en-US/ug1586

Just going over the PCI bus to the NIC costs you 500-600ns with a kernel bypass stack.

Hardware TCP offloads usually deal with the happy fast path - no gaps or out of order inbound packets - and fallback to software when shit gets messy. Widely used in low latency fields like trading

Optimising hardware to run existing software is how you sell your hardware. The amount of performance you can extract from a modern CPU if you really start optimising cache access patterns is astounding High performance networking is anothe

Most people implement them now in my field using mmap tricks so the CPU can do the wraparound for you in virtual memory. Makes the code trivial

I guess one aspect of it is that in really high performance fields where you're taking in lots of stringy real inputs (FIX messages coming from trading venues for example, containing prices and quantities) you would simply parse direct

The researchers in this case literally checked the patch after release. It costs nothing to send them a pre-release and ask the question

I don't understand why they wouldn't give a pre-release patch to the bug reporter (especially if it's someone like Google) for them to analyse before doing a final release. If they were actively working with Project Zero inst

Martin Thompson, of LMAX Disruptor fame, has I believe a novel solution in Aeron called the logbuffer, which fully formed 10+ years ago in that codebase.

Generally I find it's best to implement push operations as try_push operations and let the caller decide if they want to drop, or spin. There are definitely designs that can deal with non-POD data of variable size, although that does i

A good write up, but a preallocated MPMC queue can be built without using CAS on every push and without fixed size slots and without multiple rings. While even SPSC ring buffers are simple they are not particularly efficient in the case whe

These distributed sequencer solutions are for resilience, and they add a lot of latency because each node needs to do something like RAFT. Exchanges generally don't care aggressively about low latency, they care about resilience and fa

Why not just split responses over multiple UDP packets? Spoofing/amplification attacks are already a problem, no?

Some people don't want to block for a microsecond when their lock goes 1ns over your adaptive mutexes spin deadline. That kind of jitter is unacceptable.
