Try the test with just PowerCache on. Not likely considering I took the original 030 off to put the upgrade board on :) Just to make it absolutely clear for the fifth time so everyone knows, this PowerCache card is a CPU socket upgrade *not* a PDS expansion card (that has an Asante LAN card in it), remember this is an SE/30, not a IIci. As I stated in the last results post (may not have been clear), leaving the PowerCache switch ON and the toggling the PowerMath switch (rebooting in between) makes *no difference* to the FPU performance. I presume, seeing as it's a CPU replacement board the PowerCache switch turns off the other board funtions (50MHz FPU, 32k Cache etc.) and runs with the on-board FPU and the 50MHz 030. Does the boot process jump in speed when the Power Central CP loads when you have both switches Off? It doesn't jump in speed ever because the machine can't swap for the 16MHz to the 50MHz CPU, the 16MHz CPU is in a box under my bed 300 miles away ;). If it doesn't then the accelerator is disabled and you're using it as just a 32K cache card. As I say it more likely shuts off all the functions and just uses the 50MHz CPU and the 16MHz FPU, hence the drop in FPU performance. I think that all proves the FPU on a PowerCache card is better than the on board FPU (or the FPU emulation on a non-FPU machine). As for SANE calls I don't know unless I can locate a SANE specific benchmark or something that specifically allows SANE to be analysed.
