 ### Automating subtree synchronization
+### Implementing support for multiple machines for rustc-perf
 
+We made a lot of progress with the Rust project goal for [improving](https://rust-lang.github.io/rust-project-goals/2025h1/perf-improvements.html) our compiler benchmark suite. The benchmark suite is now able to run benchmarks on multiple machines (called collectors) in parallel. This will enable us to reduce the latency of waiting for benchmark results, and also allow us to benchmark the compiler on different architectures than just x64 (e.g. ARM) and in theory even on different OSes than just Linux (e.g. Windows). The project goal has been carried over to the next goal period. We plan to deploy the new system into production in the upcoming months.
 We have implemented a new tool called [`rustc-josh-sync`](https://github.com/rust-lang/josh-sync), which makes it easier to synchronize changes between [Josh](https://josh-project.github.io/josh/intro.html) subtrees and the main `rust-lang/rust` repository. We have migrated the existing Josh subtrees (such as `miri` or `rust-analyzer`) to this tool, which enables us to perform subtree synchronizations in a more unified way.
