Description
Please consider asking perf to record the total number of syscalls for a build, and offering that as a comparison metric. That can be really useful when doing library-level optimizations to make fewer syscalls.
It'd be even more helpful if the raw data could record the number of syscalls of each type (e.g. number of read calls).

Research direction
Start by tracing how rustc-perf records build metrics and produces comparison data. Determine where total syscall counts and per-syscall raw data would fit, then define what collected data and comparisons would constitute completion; the issue names no files or tests.
