Sure, it's low end. But emulation carries a high burden.
Here are some figures from my own tests (except the Pioneer), compiling a RISC-V Linux kernel version from December 7 using defconfig. All "native" builds on either RISC-V hardware or else RISC-V Ubuntu 20.04 running in emulation (qemu) in docker.
