The sys-perf* Evergreen project compiles the server without making use of the shared SCons cache.

• A clean build of the server takes 3 hours when using the amazon2-arm64-small Evergreen distro. (for example)
• A clean build of the server takes 50 minutes when using the amazon2-arm64-large Evergreen distro. (for example)

The amazon2-arm64 Evergreen distro is an alias which can be fulfilled by either the amazon2-arm64-small distro or the amazon2-arm64-large distro based on host availability. The sys-perf Evergreen project should instead always compile on the amazon2-arm64-large distro to reduce the wall-clock time.
