# DPDK

Hacker Approved page: https://hackerapproved.com/p/dpdk/

8 people recommended DPDK in Hacker News comments, 4 had mixed feelings and 5 criticized it, November 2025 to October 2026. It was recommended in 5 of 12 months, in 6 threads. It does not meet the Hacker Approved badge rule.

**Verdict:** People recommend DPDK for kernel-bypass packet processing at very high speeds, including 400G in VMs. The most common caveat is that tuning is hard, especially on cloud hardware.

Summary written by Claude from 19 comments. It was written before the November 2026 recount, and 18 of those comments still count.

## Why people recommend it

- Long-term choice for demanding workloads (3 comments in the sample): "things like DPDK are the long term best choice" ([source](https://news.ycombinator.com/item?id=49824432)) "there are use-cases better suited to DPDK" ([source](https://news.ycombinator.com/item?id=49229115)) "DPDK-based tools are great" ([source](https://news.ycombinator.com/item?id=49240737))
- High speed, low latency packet processing (2 comments in the sample): "The first time you hit top RX speed (2x400G my latest) with only one busy core (yay DMA engines) is always a thrill." ([source](https://news.ycombinator.com/item?id=49236416)) "with dpdk I got something working at full blast 400G in VMs with little (but finnicky) work" ([source](https://news.ycombinator.com/item?id=49230408))

## What people warn about

- Hard to tune and use (2 comments in the sample): "Differences between tuning and hardware types has been a nightmare with DPDK especially with cloud deployments." ([source](https://news.ycombinator.com/item?id=45839321)) "DPDK is much harder to use than XDP" ([source](https://news.ycombinator.com/item?id=45823618))
- Bypasses kernel; interface invisible to it (2 comments in the sample): "the network interface is invisible to the kernel, making non-accelerated traffic on said interface tricky" ([source](https://news.ycombinator.com/item?id=45824682)) "DPDK is a huge framework that invasively bypasses the kernel" ([source](https://news.ycombinator.com/item?id=45824127))

## The badge

A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it. Health and money products are never badged.
