🌊🌊🌊 Hochwasser 🌊🤽🌊

Highly efficient, distributed Pixelflut client.

Hochwasser brings back the /fun/ in social DDoSing!

No more micro-ddosing: Get Hochwasser now and experience highs never seen before!111!

• Can send static images, text, generated patterns (animations upcoming)
• REPL enables fast iterations
• CnC server + client architecture (it's webscale!) (can also run in a single process)
• Faster than sturmflut (in some benchmarks at least)
• No dependencies (pixelflut apparently was considered a primary use case in the design of golang's stdlib 👍)

build / install

1. have a go installation >= 1.12
2. go get github.com/SpeckiJ/Hochwasser
3. go install github.com/SpeckiJ/Hochwasser

benchmark

The following benchmark was run on a max-spec X280 against version d4c574b.

I could not figure out what the performance bottleneck is, but it doesn't seem to be CPU limited, as turbo-boost doesn't kick in.

To reproduce, run the following commands in separate shells:

iperf -s -p 1234
go run main.go -image benchmark/test.png -connections 10

55 Gbps on average! 🌊🌊🌊

sturmflut (./sturmflut 127.0.0.1:1337 benchmark/test.png -t 10, version 8ec6ee9) managed to get 48 Gpbs throughput on this system.

Hint: Benchmarking throughput against the pixelnuke server is pointless, as performance is then CPU-limited to ~1 Gbps by the server. Using iperf removes the server limitation. This also means that these metrics of several Gbps are far higher than realworld scenarios.
