This workload builds wasmer. Wasmer is written in Rust and is a WebAssembly runtime implementation. Looks like segments running on all cores and others dropping lower. Overall build is pretty quick.
Topdown profile shows on average frontend stalls are higher.
AMD metrics confirm frontend stalls account for more than half the slots. On average on_cpu is 10 cores.
