When I run `sh validate -legacy`, towards the end I see stuff like this Performance Metrics (test environment: local): Conversions(normal) runtime/bytes allocated 107696.000 DeriveNull(normal) runtime/bytes allocated 112050960.000 InlineArrayAlloc(normal) runtime/bytes allocated 1600041088.000 InlineByteArrayAlloc(normal) runtime/bytes allocated 1440041088.000 InlineCloneArrayAlloc(normal) runtime/bytes allocated 1600041248.000 ManyAlternatives(normal) compile_time/bytes allocated 840985728.000 ManyConstructors(normal) compile_time/bytes allocated 4540766560.000 MethSharing(normal) runtime/peak_megabytes_allocated 2.000 MethSharing(normal) runtime/bytes allocated 480098136.000 MultiLayerModules(normal) compile_time/bytes allocated 5856970504.000 ... It is intermingled with other apparently unrelated output. What should I conclude form this? Is it good or bad? By what amount have these figures changed, and relative to what? How can I run a single perf test? Thanks Simon
