I Use Zip Bombs to Protect My Server
These days, almost all browsers accept zstd and brotli, so these bombs can be even more effective today! [This](https://news.ycombinator.com/item?id=23496794) old comment showed an impressive 1.2M:1 compression ratio and [zstd seems to be doing even better](https://github.com/netty/netty/issues/14004).
Though, bots may not support modern compression standards. Then again, that may be a good way to block bots: every modern browser supports zstd, so just force that on non-whitelisted browser agents and you automatically confuse scrapers.

How TBMQ Uses Redis for Reliable P2P MQTT Messaging
To overcome this limitation, we migrated to Lettuce, an asynchronous Redis client built on top of Netty. With Lettuce, our throughput increased to 60k msg/s, demonstrating the benefits of non-blocking operations and improved parallelism.

New scalable, fault-tolerant, and efficient open-source MQTT broker
We use Netty (https://netty.io/) as the source of the MQTT communication, and we build the MQTT features the MQTT broker should support ourselves on top of that.

Modern Async Primitives on iOS, Android, and the Web
In this space, we also have the somewhat related term blocking. Java's NIO library is one well-known non-blocking tool used for managing multiple tasks on a single Java thread. When listening to sockets, most of the time a thread is just blocked, doing nothing until it receives some data. So, it's efficient to use a single thread for monitoring many sockets, to increase the likelihood of the thread having some actual work to do. The Selector API does this but is notoriously challenging to program well. Instead, developers use frameworks like Netty which abstract some of NIO's complexity and layer on some best practices.

An investigative journey through concurrent data structures
DirectByteBuffer exhibits an intriguing behavior: it deallocates its backing memory during the finalization process, which occurs after garbage collection (GC) cycles. This poses an issue if your system is conservative with on-heap allocations, leading to infrequent GC cycles. In such cases, there could be a significant delay between the time the memory becomes unreferenced and when it is actually deallocated. This behavior could, in some respects, mimic a memory leak.
This is why some libraries hacks into DirectByteBuffer to deallocate memory explicitly, bypassing the finalizer altogether. For instance, the Netty library has implemented such a workaround, see Netty as an [example](https://github.com/netty/netty/blob/795db4a866401aa172757b95...).

Scaling to ~15K requests per second with Java – Part 1
Apologies replying to myself, but Netty, which underpins many of the popular Java backend frameworks, see backward compatibility as more important than supporting green threads.
https://github.com/netty/netty/issues/12816
It'll be interesting to see who (if anyone) picks up Netty's mantle in the Project Loom world.
