Memspeed is saying:

READ 30.1 17.3 17.3
WRITE 20.0 20.0 20.0

All three jumpers are set.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Hi Steve

Interesting issue. I have not seen that personally with my Mach64 but I guess it could be me not paying attention.

One thought - I wonder if the VME fix to save 1 clock cycle per transfer would improve this?

Atarian Computing has a good guide on this ... keitfaster

I haven't plucked up the courage to tackle the fix on my TT yet as its a bit precious to me and I need a lot of spare time to make sure I get it right and time is a rare commodity :)

Thanks for the advice, but I think my TT already has that done. I don't know if you run Mint, but a good test is to see how fast the xaaes/teradesk desktop comes up. In 16bit colour it takes about 30 seconds for the desktop to appear, in 256 colours its instantaneous.
