Benchmarking software

Hi All,

I’ve been having a bit of a play with rpcemu on my M1 Mac Mini. (Version 0.9.3 IIRC), and it’s all been good fun, it’s nice to see the desktop again.

However, I’m kind of wondering how fast it all goes as it feels like I might be able to wring a bit more speed out of it. So, to that end, what’s the current benchmarking software de jure? I seem to remember a !Sick from my childhood and maybe an !ArmSI, are these still things?

I’ve been running RISC OS Mark 4 (The confusingly named ‘RISCOSMark5’ BASIC file as I assume that’s for RO5?)

I’m currently getting the below, which seem nice (I’d’ve killed for that IO speed way back when!), but I reckon I can get it to go a bit quicker yet…

But as I say, other things with other numbers in would be good too. :)

Chris Hall some nice benchmarks and figures from other machines at https://www.svrsig.org/HowTo.htm under Benchmarks

Hi Ian, the processor speed seems low for such a fast base system; I get 580% running 0.9.4 Recompiler on a fairly elderly Acer laptop (Intel i3 @ 2.6GHz, IIRC). RPCEmu 0.9.4 is /much/ faster than 0.9.3.

Hi George,

Thanks for that, I didn’t realised 0.9.4 had an ARM64 recompiler in it.

I’ll stop writing mine then. :)

(I’d managed about double the speed of the interpreter, but I’m only recompiling a few of the simple logic instructions at the moment).

Doh!

Nah, not really. I wasn’t writing it to bring ARM64 support to rpc-emu, I was writing it to see if I could as it’s an interesting challenge. (I’ll probably carry on with it for a bit, then go see how close to the official one I got).
