Well SysInfo doesn't load anything during speed measurement and there was no PCMCIA involved here - and A600 is just a datapoint measured by Mr. Wilson to compare the other Amigas to. (You know, the list A600, A2000 33% fast cos of real fastmem, A3000 25 Mhz, and so on.)
The expectation would be that all things equal, an A500 with chip+slowmem would perform exactly like A600 with only chipmem - no matter how the benchmark is written, really. I.e. 1.00, not 1.03.
But with the only thing changed, Kickstart version, the same hardware configuration reports different results for the same benchmark being run.
I don't know what's more baffling, the 1.03 score for KS13 or the difference from just switching KS version. I'd expect SysInfo to turn off interrupts with Exec, but if so that makes it even harder to pinpoint what it is
