It's not surprising in the slightest, no matter how it's "optimised". 32k modes require more bandwidth, by simple virtue of being larger. Furthermore, RISC OS code won't make use of the LDRH/STRH instructions, meaning there's no atomic 16-bit access to memory, which is clearly going to be slower than a single byte access in 256 colour modes, and comparable to a single 32-bit access in 16M colour modes.
