Even if it was, it is unlikely to help you. You need to drill into what is going on in the
benchmark. It is hard to do based on your current explanation, because there is no benchmark code.

Profile the benchmark with -prof perfasm at different workload sizes, and that should highlight what
is the final generated code, which would give you some idea what might go wrong.
