We have recently observed performance improvements for certain RPC throughput tests on Kasli-SoC after upgrading the rustc and LLVM versions for the artiq-zynq firmware.
The sample size is 1000 (20 samples per kernel, 50 kernel runs). Error bars are standard deviations.
Sending 1MiB payloads as bytes to the core device has a 46% higher throughput in the beta compared to ARTIQ-8, and this increase of 46% is also observed for 1MiB i32 arrays. The improvements were bisected to this LLVM upgrade from 11->13.
Data was obtained by running tests in test_performance 50 times each and accumulating the results with a simple script. The Kasli-SoC variant is demo.
