JUring read performance just got better!
📈 426% faster @ 4KB with registered files
📈 231% faster writes @ 4KB (single threaded)

But write performance gets funky at 20+ threads... and FileChannel actually beats it! Anyone have debugging tips for high-concurrency writes? #Java #Performance

Just hit 342% faster I/O than FileChannel @ 4KB with JUring!

Using registered files + Java's FFM API for truly high throughput file operations, and this is just the beginning!

My Java io_uring lib is 57% faster than FileChannel on average and I keep re-running the benchmarks because these numbers are crazy good! 🚀
Linux only but Java + io_uring is a nice combo

Spent way too long figuring out why my io_uring bindings wouldn't scale beyond 15 threads... turns out my system doesn't consider 34,500 concurrent open and close file operations a "fun exercise"

After fixing a zero termination bug, JUring (io_uring bindings for Java) does 4K random read local files 75% faster and remote files 87% faster than FileChannel!

#Java #io_uring

Been working on bringing io_uring to Java these past few weeks. Started as an experiment with the Foreign Function API but got a bit carried away :)
