Fast, platform-independent speedups
“I think they actually have one of the better setups for allowing someone to write fast code that is platform independent.”
Comment from 10 Mar 2026 in “RISC-V Is Sloooow” “I've been using the Vector API in Java to get some massive speedups for flowfield generation.”

What people warn about
Each mark is one comment
Little mainstream adoption
“I really don't think the prediction that the vector api will become a mainstream feature soon is true.”
Comment from 7 Oct 2026 in “Mastering SIMD with Java Vector API” “a standardised API nobody uses because it came 10 years late to the party”
Comment from 24 Oct 2026 in “TornadoVM 7 Enables GPU-Native Workloads from Java Applications” Late and still incubating
“a standardised API nobody uses because it came 10 years late to the party”
Comment from 24 Oct 2026 in “TornadoVM 7 Enables GPU-Native Workloads from Java Applications” “its on the twelth incubation and there's no end in sight”
